I read the entire thread. High-IQ ideas, but I have to disagree with OP.
I'll restate OP's thesis: Incels should try to convince liberals and leftists that we are another marginalized group. We should earn their sympathy. Then steps will be taken to correct the marginalized position of incels.
The problem with this thesis is that enabling incels to ascend requires foids to PAY A COST, i.e., have sex with sub-8 males. That gives foids the ick. Leftists and foids are all about helping the underprivileged and marginalized as long as they themselves don't have to pay the cost. For example:
Homelessness: Foids are fine with motels and shelters housing the homeless. They will say that housing is a human right. But foids would never let homeless people live with them in their own homes. Gross. They would never incur a cost voluntarily.
Food: Food is a fundamental human right. But a foid working in HR in New York City would never agree to work on a farm to provide food, a human right, for starving children in Africa.
Defund the police: Leftist academics will demonize the police while living in rich college towns with very low crime rates.
Climate justice: Corporations should do more to address the climate crisis. Jeff Bezos needs to do more. Meanwhile foids will buy stupid consumer goods shipped all the way from China. Foids need retail therapy and self-care.
LGBTQIA+: If a woman doesn't want to have sex with someone in the LGBTQIA+ community, she doesn't have to. The queer agenda does not impose a cost on any foid.
(Also, I don't think government-funded prostitution is a solution to inceldom. Almost any incel living in the West can save up $500 in a few months and fuck a top-tier prostitute. Instead, for me and many others, a one night stand with a whore is not what you we're looking for. Instead, we want a monogamous, traditional relationship.)
I'm gonna start at the bottom:
For me, state sponsered prostituion is not really an important goal. It seems fair and obvious in some ways, saving multiple hundreds of $ on the regular would be no small matter for many of us, but it ultimately doesn't get to the root of the problem. BUT if we would get to a place where something like that is being openly discussed in the public discourse, that would mean men's plight and the inflexible nature of our problems would have to have been acknowleged by society as a whole.
As you wrote, one of my core goals is for everyone else to face some of the basic facts that make up the fundation of the blackpill. Because once it it is clear that we are born disadvantaged and that there is a hard limit to how much we ourselfs can change about our position in life, fairness dictates that we ought to recieve some help and empathy.
For now, most of the progressive insanity is always pro-women. There are some exceptions, e.g. trans women in female sports and bathrooms or how the rent / buying prices for houses in America are raised majorly by the fact that all whites and asians are forced to compete for living space away from Black & Lation neighbourhoods.
But those are exceptions. What my OP was based on is the assumption that men's plight in the western world will continue to worsen and that sooner or later there will be some counter reaction. Lefties still want to be elected and they wouldn't want to loose a significant portion of male votes to their opposition. On a more direct level, as more and more men start to speak up against leftist oppression, pressure to find a compromise will start to build up.
If men's condition as a group becomes bad enough, the left will have to make concessions. The normies are slow as fuck in the head, but this whole insanity is not that old and it has not been in the forefront of politics for that long. I went through the first decade(s) of my life without hearing the word "transsexual" once.
By now, there is some push back being organized amongst the general public. A lot of this shit is not very popular amongst the masses.
So, at least consider preparing for the possbility that at one point, there will be an opportunity to improve our situation by cooperating with the left. A compromise, where they offer some kind of sympathy / societal recources in exchange for not losing the majority of men to their opposition.
Under these conditions, I think that the general pattern of "always pro-women" will not be that rigid anymore. Up till now, most men mindlessly supported their own exploitation and degradation. We haven't seen yet how the left deals with real resistance, because up till now their own base was always mostly united behind shared values. But many of the men on their side are ugly, low status freaks and some of the most empathetic women are on their team as well.
I believe there will soon be internal conflict between leftist camps and men will start to speak up more confidently about their problems. We already see a lot of it online. It takes time for ideas to spread through large portions of the population and these retarded normies first have to mistakenly adapt redpill believes before some of them will travel further down the rabbit whole towards blackpill insights.
Though, since everyone would be hiding what they truly believe about taboo topics, we should expect the amount of people already believing blackpill ideas to be much bigger than it seems from outside observation.
There is a term for this in psychology. "Preferance Cascade". Everyone hates the king, but nobody says anything because they are scared. From the outside it seems like everyone is on board with his rule. One day, a small revolt happens. And suprisingly, it isn't immediately put down by the royal forces. Suddenly, in cities all across the country similar revolts mobilise spontaneously. Why? Because the people were already waiting, ready to do something. But they wouldn't shoulder the risk of being the first mover themselfs. They needed to see someone else do it for them and for that person to succeed or at least not fail completly.
Something similar is what I hope might happen around leftist ideology. And if such a chance presents itself, I don't want most men to be shackled to some retarded conservative politician or some other useless label like fascism, nazism, right-wing politics, etc.
Those all have accomplished nothing for us. And I believe them to be doomed to lose, based simply on the type of person they attract.
The upper rangs of the left have all the mentally-ill ideologues. The right has all the individualistic, self-sufficient normies and career politicians. The left has the type of person that possibly could be invested in helping us in our struggle. If they can be made to see it for what it is. And for that to happen there will first have to be some external pressure.
It's not like that is the only thing I would want to try, but it is an option I think should remain on the table. Try everything, do more of w/e works best. But if we never try converting leftists because we think we already know they will never go for it, then we could be missing out on a possible way out of our misery.
