The only problem of feminism I've seen thus far is "making men the enemy". You can hardly hear a feminist make 5 sentences without referring to men in 4 of the sentences. The feminist movement has been turned to an anti-men movement. Any woman that makes a wrong relationship decision and get hurt in the process will easily convert to a feminist and start poisoning the hearts of other gullible women against men. It's so hard to find a happy feminist.
Oo do they actualy exist? In the 70's the feminist movement was about equality of the sexes. Now it has become a Female > Men movement. We will soon need to start a maninist movement :P
