To answer your question, CB, I am most critical of the versions of feminism which elevate "Woman" to the status of a collective social category that seeks "representation" at the table of political power. So-called "First Wave" and "Second Wave" feminists tend more strongly in this direction, but I've seen a few self-professed "Third Wave" feminists fall into this tendency as well. In my experience, these are the sorts of feminists who are most likely to get caught up in the moralistic "privilege-checking" of "call-out culture."
Strictly speaking, I don't think that the various "waves" of feminism have any basis in reality, but the fact that some feminists feel the need to make such distinctions helps to illustrate the point that they aren't all unanimous about what "feminism" actually is. There are certain feminists that I think are completely out to lunch and others that I think have some genuinely interesting and worthwhile things to say. For instance, in her book Gender Trouble, Judith Butler (who many would classify as a Third Wave feminist) devotes herself to deconstructing "Woman" as a collective social category and, in stead, argues for recognizing each individual woman as unique unto herself.
An interesting article on this subject is "Beyond Feminism, Beyond Gender," from Wolfi Landstreicher's Against The Logic of Submission series. You can listen to it here in audio format:
