I believe that feminism started out as something good (referring to the text-book definition and history), but as most mass-movements it developed some strange branches that hurt the original idea more then they do it good (because they are perceived as what feminism is, even though it's not).
The problem is not feminism, the problem is what (some) people make out of it, and how it backfires (or probably will). And this is because women are different from men, they will never be "equal" (it starts with physical differences and ends with the way of thinking, which just is different - though one is not better or worse than the other, just different as in: not the same), so you cannot make them equal (and especially not through regulations). Of course there is not a shadow of a doubt about having equal rights and so on.
The problem starts when everyone is forced into some new ideals which even the women I know think are stupid ... that's not feminism by the text-book definition, but it is what a lot of people connect with that word ... so there's feminism and there's "feminism".
