Most of them have at least a brother or a father that they like. Or a coworker or even an old boyfriend and not a few best gay boyfriends. As far as I've been able to determine, most lesbians don't really hate men as a class. This has puzzled me for some years, and I finally came to a personal conclusion about it. It comes down to how we sort things.
Straight women discard the BAD ones, one at a time, as each man screws up.
But the rest of mankind is still out there untested, and unmet, and each of those until tested is still a potentially nice guy. And even these events evoke sadness and feelings of loss and the nagging thought that the love of a good woman could have saved the man somehow, had he just listened to reason. Lesbians, on the other hand, harbor a sneaking suspicion, a basic distrust, of all men on sight, and we let the GOOD ones in one at a time as each man individually proves himself to be worthy of our time. This doesn't translate that we hate them. It translates that we are withholding final judgement.
