I dunno man, I'm sure they would feel shame if they made a grown defenseless man cry. Have you tried just crying? When they start making fun of you for crying, then fling their own shit at them and make fun of them for reinforcing toxic masculinity. That's the fucked up thing about bitches. they'll bitch about "toxic masculinity" yet are completely aroused by it.
While I don't think crying is a great idea, nor is using the language of feminism because as Orwell correctly pointed out, whoever controls language controls thoughts.
Having said that, let me give you an example of "throwing things back in their face" that is a little different from the usual examples.
My mother and I used to have some of the worst fights you can imagine. This went on for 20+ years until one day I realized that if I were to accept her arguments, they would amount to that I'm a horrible person at an intrinsic level and that every negative feeling I have had towards her was invalid because of this. That is a terrible thing to accuse someone of. She was so swept up in the emotion of fighting, that she was telling me everything I feel is wrong and that I was attacking her by claiming she was the source of them. She would push me even closer to going ER by denying everything she has done or said in the past as well.
Anyways, I'm going to such lengths to illustrate the nature of her argument to highlight what it is I realized. That if I accepted her argument as true - on the surface conceding the fight - she wouldn't be able to hide from what she was actually saying. We would fight, she would say the usual shit, I would get enraged, but instead of continuing to get baited into her escalation, i "threw it back her" by agreeing.
"You know what? You're right. I am just a bad person who was born bad. I'm crazy and delusional because you've never done anything bad. I'm just an awful person who doesn't deserve to have their feelings acknowledged. I deserve to be miserable, angry and sad forever because I wasn't born any good. In fact, I'm sorry. I'm sorry you had to have such an awful son." and etc.
Let me emphasize, this is said with absolutely no sarcasm. This may be difficult for people to do if they're not used to training the mind to adopt different ideas and their supporting mental frameworks at will. It isn't that I do or don't believe it - it is more like a thought experiment. I accept the argument as true so I can follow them to their logical end and communicate that.
In the case of virgin shaming, we at least have the advantage that it is true, the virginity part at least. When it comes to shaming, the accuser wants/expects you to fight against the label, because that is what an ashamed person would do. Instead, if you were to accept their label and just follow it to it's logical end - well, that person is going to have to face a much darker realization as to what they're actually doing and what that says about them. As we all should know, most everyone thinks they're a genuine good person, oblivious to the fact that the only good things they ever do are strictly for people they get something out of.
It really taps into something deep in our psyches. People have a powerful negative gut reaction to seeing themselves being mean and abusive. These people are mean and abusive all the time, but they're never forced to face themselves when they're doing it. It is interesting to me how all humans play these vicious social dominance games at the instinctual level, but if you ever do something that raises it to the conscious level, people become ashamed of themselves. Maybe it is because there is an acknowledgement of the social dominance standings of the people involved ("yea, you're right, I'm a virgin loser who deserves to be sad and alone forever, you're an attractive winner who has tons of people that love you because you're so great, etc"), but that conscious acknowledgement releases the emotions that drive people to feel the need to assert the social standings by bullying you.
Anyways, I'm just theorizing at this point, but it is interesting to me at least. I need to experiment more with these ideas in different social contexts and see what happens.
