Okay, let's take Creationism, or Fundamentalist Christians, like Pat Robertson... Obviously, all Christians are not Creationists, nor are they all Pat Robertson. Not all Christians agree with Pat Robertson. Lots of Christians accept science and the truth of Evolution.
If someone tries to conflate all Christians, particularly progressive Christians, with Pat Robertson, they're in the wrong. If someone tries to imply that "Christians" all think the Earth is 6,000 years old and Jesus rode a dinosaur, they're wrong.
But here's where the logical fail comes in;
I've seen some Christians on DU repeatedly remind us (rightly) of the above- all Christians are not creationists. All Christians are not Fundamentalists.
Yet then they turn around, in a situation where Fundamentalists are being criticized, or creationism is being ridiculed, and they say "STOP ATTACKING CHRISTIANS WITH YOUR ANTI-CHRISTIAN CHRISTIAN ATTACKING!!!"
See the problem?
We have the EXACT same situation with certain ideological sub-factions of "Feminism"; Not all Feminists agree with Andrea Dworkin that "men must give up their precious erections". Not all Feminists think Catherine MacKinnon was right to pal up with Ed Meese against free expression. In fact, most don't. I don't, and I (still) consider myself a "Feminist", even though some have told me I can't.
If someone criticizes the writings you reference above, or point out that "Twisty" has ideas about consent (namely, that consensual sex between men and women doesn't exist) which are fucking noxious and only serve to muddy what should be clear messaging around rape; or if they make fun of Solanas or Dworkin or their defenders....
you see where this is going. They are accused of "ATTACKING FEMINISTS" and hating women and all manner of nasty-sounding gibberish.
No, the folks in question are a small minority who do NOT speak for ALL Feminists or women-in-general. That's the whole point. But they desperately want to assert that they do.
