"Again, I come back to my question about what is the impact on "men" if a few women "hate" them - how does that "hate" manifest, if at all?"
For me, I've just got better things to do with my free time (given that I spend a lot of my working time surrounded by men) than engaging with men. They're just not that interesting or worthwhile.
If you're a feminist this is enough to get you labelled a man-hating feminist (and probably a lesbian as well). If you're a lesbian, that alone can be enough that you get asked repeatedly (usually by men) why you hate men so much.
And the conversation on this thread got me thinking about the many times a strange man has tried to talk to me in the street. You are not allowed as a woman to just have better things to do, be preoccupied, be talking to someone else, and so on (although mobiles and mp3 players have probably changed some aspects of this interaction).
No, I don't hate you, no you haven't offended me (most of the time), or been offensive, you're just not that interesting to me and I have better things to do/think about.
Which is, I suppose, about the biggest insult you can level at the entitled sex! Because hatred itself shows you how much impact they have (just in a negative way, but hey, some people aren't that bothered, positive/negative, at least someone now knows you exist!).
