1) 'Gender critical feminism' is an identity politics movement based on the idea that the two biological sexes are two opposing classes, with males historically oppressing females. This has the same structure as critical race theory, and by definition, is identity politics. Too many people seem to misunderstand 'gender critical' simply as being critical of 'gender' philosophy. This is not what 'gender critical feminism' actually is.
2) Disney might not have been 'canceled' by DeSantis, but what happened should have concerned free speech activists, no matter what we call it (there seems to be no clear consensus as to the 'boundaries' of cancel culture, other than the term vaguely meaning punishing people or entities for their exercise of free speech). Even if we decide not to call it 'cancel culture', what DeSantis did was still an exercise to limit free speech in some ways. Disney had no actual power to repeal the law, DeSantis could have just ignored them. He could have even criticized Disney in public, using his own free speech. Instead, he chose to use state power to curtail free speech, in that if Disney wanted their benefits back, they would probably have to stop upsetting DeSantis. This sets a precedent that free speech activists should have been quite concerned about.
