This oversimplifies things a bit. I don't hate the concept of feminism at all -- indeed, there are plenty of aspects I agree with -- and there are even some radical feminists who can be reasonable. What I do hate, however, is anyone who misrepresents other groups and the things they enjoy in order to further their own agenda. I also hate when people who follow a particular ideology blindly hate on anyone who holds a different viewpoint, and refuse to compromise or "live and let live". This is by no means exclusive to feminism!
