"Do feminists on this thread only know a handful of nice men?"
The sad truth is, kins, that apart from a VERY small group of men with whom we spend a lot of time, such as our husbands and immediate family, we cannot possibly know if they are nice or not. We cannot know how they behave towards the women in their lives behind closed doors. We cannot know whether they make sexist jokes while out with the lads. We can, however, be fairly sure that they laugh along with these sexist jokes and be doubtful that they would stand up for women by denouncing these jokes. We cannot know whether they would continue to push a drunk women for sex even if she is clearly incapable of clear consent.
And even then, we might be wrong. Our DH, our brother, our uncle, could well turn out to be an abuser or an ignorant rapist ("of course it wasn't rape, she was too drunk to say no! And she was all over me earlier in the evening").
It comes back to the basic fear that women have of men. We have this fear for a reason. Because we never truly can know if a man is "nice" or not.
