The point here, surely, is that if you are a woman - and have thus experienced all kinds of unpleasantness from men - you're not in a position to be deciding "ah, that one's OK, but this one isn't". At that point, ALL men are potential threats. I think this is a mindset that we men, not having to spend large parts of our lives in the same state of threat, just don't get, at least not without a lot of mental gymnastics and hard thought. Yes, there is probably a bit of mansplaining in that lot, but I hope I'm vaguely on the right track.
And, to the extent that we don't call out our mates on unpleasant behaviour (particularly towards women)), we ARE ALL part of the problem.
I don't particularly care for the more personalised criticisms which sometimes surface, ie. suggesting that I, singular, am part of the problem, but that is very different from accepting that, as a gender overall, we have some serious heavy lifting to do if we are going to ever get to the point where the problematic men can be seen as an outlier, rather than an indistinguishable part of the group.
