But every liberal I personally know is not like that, and I know a lot of them. Do I ignore every single one of them and decide some overprivileged douches living in echo chambers are more representative of the group, when that goes directly contrary to my own experience? That is not likely. (I don't actually know if the PA guys identify as liberal.)

There is no question that there is a horrible and disgusting trend of liberals being assholes, and lately of liberal men (and Naomi Wolf) rape apologizing up a storm. But considering someone who is very much not a liberal wants to pass a bill making women have to prove they were forcibly raped (rather than any other kind of raped) before the government will pay for their abortions, it's not liberalism I'm ascribing this to.

It's rape culture. Liberals live in the same world as everyone else. They absorb the tenets of rape culture as readily as anyone else. We're just more shocked when people we expect not to be raging assholes turn out to be raging assholes. Also, we tend to try harder to talk to them, because we believe they will listen, because they have listened in the past. Unlike people who deny women's basic bodily autonomy, who use the word "feminazi" in seriousness, and who actually believe that there was racial equality in the U.S. as soon as it was founded.
