I think a straw feminist is meant to be a character (a fictional character, or a persona played by a troll, or an imaginary opponent), not a person sincerely expressing their position. So Daly and Dworkin weren't (or kept up the charade for quite a long time). Straw feminists say stupid and offensive things to make actual feminists look bad. Bugmaster meant that the quote sounds more like something someone would attribute to a feminist in order to make feminism look bad, than like something a feminist would say.

But there are in fact fringe feminists who are indistinguishable from their parodies.
