The fact that your first instinct is to point out that women over 50 are the fastest growing homeless population is exactly the problem. Like, hello, 83% of the homeless are men. This should be the main point of discussion.

But it affects men, so feminists simply pretend this statistic doesn't exist.

Feminists cannot claim to fight for equality while ignoring every single way that men are disadvantaged. I think that's quite a simple argument to understand. This is the primary reason people generally don't believe that feminists fight for equality.
