Really? How many anti-feminists are there on Hacker News? Very few, I'd say, especially as such views tend to be immediately downvoted and flagged into oblivion.

There are however plenty of people who are disturbed by the systematic way certain minorities attack and destroy speech about ideas that are, objectively, commonplace and popular (just look at opinion polls).

Even the top voted comment on this whole thread talks about disquiet over censorship whilst ending by saying they're a left leaning socialist. Of course, this statement should not be necessary to make, but it is - it's a form of "don't shoot I'm on your side".
