I don't think you can tell anyone what they can and cannot call themselves. If people call themselves feminist, communist, capitalist, socialist or whatever philosophy they align with. That is their freedom of choice. If their action conflicts with their philosophy then politely point out the contradiction and ask for an explanation.
I don't think any woman on this forum claimed that they hated or dislike all men. The harsh stances were against sexual harassment and not men. Let's face it even legal systems struggle with the definitions of crimes, misdemeanors and non-offenses. We can't fault lay citizens for having strong opinions of their own. Let's debate the differences in definitions, not condemn people for having an opinion.
Some men are dogs and some women are bitches. I think that's a statement we all can agree with. There is good and bad in all groups. I don't believe the intent was to call all men dogs, but just point out that some men can be. However, I think in the heat of debate people took it to extremes. Now you can fixate on one misunderstood statement amidst dozens of other good points or you can look at the big picture. It's a personal choice.
Finally, it still doesn't make it right to misuse "feminist" as a derogatory term. Words like communist, homosexual, transgender are neutral at best. They have a meaning that isn't negative or bad in anyway. But some people misuse such terms as insults - commies, homos, trannies etc. Lets not make it OK to redefine words as insults. If people do misuse words, lets educate instead about what the real meanings are.
