Are women dominant subreddits extremely sexist or am I biased?

Although I agree how women have been treated unequally since the beginning of humanity, I feel like most of the posts there are unfair. Many are about ranting how men treat them bad, how men should change and how men are wrong. Do many women really feel that strong hatred for the inherent value of men or is it because we are on reddit and the extreme individuals tend to be the vocal minority here?
Or hopefully I am just a biased man who only sees the posts that I feel offended.
