I was always "forgotten" especially when foids were the ones making the guest lists
Yeah because you are a genetically inferior person that no woman wants to propagate her genes with. All of us are. And men likewise don't want your genes to propagate because their biological programming tells them that the species is better off without your genes.
Going to parties, or bars, or clubs, is a social ritual humans pass through in order to meet people of the other gender and reproduce with. If not that you meet people through your social groups and do a "mini-ritual" where you take them out to dinner or go dancing with a person of the opposite gender. And the fact that you aren't invited means that people are subconsciously thinking "yeah you are genetic filth, you don't deserve to reproduce." This can be either physical inferiority or social inferiority (often the result of mental genetic inferiority).
I remember when I was in high school, we had to run on the track for gym class. And this track was small and next to these woods, and occassionally, there would be deer just sitting there.
One day, there were like three deer all sitting next to each other, and this one deer kind of out away from the others. This deer had its tongue sticking out always; it was either sick or something was wrong with it.
Those three deer made a conscious effort to avoid that one sick deer.
We are all that one sick deer.
We are the one that can't just be killed off or whatever, so people drag us along while keeping their distance.
