It says a lot that feminists are more offended and concerned by women not being served first in restaurants then they are about male homelessness or prostate cancer.
Why do you think that way about women, can you tell me more?
It's just my opinion that women are bitchy and don't give a shit about men, because there is no other way to explain why is it so important for women to be served first in restaurants.
I do understand your frustration towards homelessness and prostate cancer, but why would feminists insistence of being served in restaurants an obstruction of those issues you have mentioned? It can be possible that the problems you have mentioned are not on the priority list of feminists but it doesn't mean that they do not support them. So instead of thinking that feminists are enemies, try to tell people that you encounter your issues and see if they can be of help to you.
