I think a large part of the problems people have with feminism is the hangover from third-wave feminism, which basically degraded into calls for Matriarchy to replace Patriarchy and anti-male sentiments. This is not helpful, neither for the cause of equality nor feminists themselves.
I will point out that it does appear that this is a minority of feminists, but as with all these things, they tend to be the most vocal. Which is why we can't have nice things.
