It's very short, so go read it and come back.
I agree essentially with Marcotte's points. I take issue with her refusal to call the anti-trans radical feminists by their chosen name. They still exist, and they still call themselves radical feminists -- they were recently profiled in the New Yorker. And, more to the point, they really are one modern splinter of the radical feminist movement of the 60's and 70's. To deny them that name is a little like saying that the FLDS have no business calling themselves Mormon.
On the other hand, Marcotte is totally right that those radical feminists are not anywhere near the mainstream of the feminist movement. One can certainly argue that they aren't the true intellectual heirs of the earlier radical feminists. Marcotte is also totally right that the original radical feminists brought us a lot of fantastic ideas that are now completely mainstream, at the heart of current feminist thought:
It was not enough to pass the ERA or legalize abortion, they believed, but we should also talk about cultural issues, such as misogyny, objectification, rape, and domestic violence.
Personally, I can't help but feel like "Yay, my team won!!" As I wrote the other day, on the issues I cared about, my position won the mainstream, and sex-positive feminism succeeded in making itself irrelevant.
But the other side won, too. Their bad ideas, like trans-women not deserving to be seen as women, plus the items I mentioned the other day, have been stripped off and shunted to the margins, and their good ideas have won the mainstream of feminist thought. They also succeeded in making themselves irrelevant as a separate movement.
It's the textbook example of a win-win situation.
