That question often pops up, especially from new visitors. After all, thuis is r/MensRights. Our subreddit description says

At the most basic level, men's rights are the legal rights that are granted to men. However, any issue that pertains to men's relationship to society is also a topic suitable for this subreddit. Men's rights are influenced by the way men are perceived by others.

I should know what that means. I was one of the people who wrote it. And it explains why we talk about feminism.

Feminism is the belief that women, as a group, have been and continue to be abused, exploited and oppressed by men as a group.

That's my definition of feminism. Of course, there's more to it than that, but that's the bit that matters here.

Put those two statements together, and that's the reason we spend so much time talking about feminism.

I've made this post sticky, because it's a reply to the other current sticky post. I think it makes a good companion piece.
