Some of them are pretty radical.

"you can't be *-ist against the majority/privileged/etc.";
learning a language and then speaking/writing it is cultural appropriation;
(separate but related: cooking, or even just enjoying various ethnic foods is cultural appropriation);
(also separate but related: little kids shouldn't dress as their favorite Disney characters for Hallowe'en unless they happen to be of the appropriate race);
changing historical documents to expunge sex-assigned-at-birth and name-assigned-at-birth;
equal rights and responsibilities (e.g., selective service, rape definitions, alimony definitions, ...) is misogyny, or at the very least an unbecoming reaction to the endowed truth that "loss of privilege feels like discrimination";
(separate but related: it isn't sexual assault when the male participant is the one who is under-age/in a lesser power dynamic/intoxicated);
the currently on-trend blanket statement that "voting Republican is *-ist" in any context;

(And these are just mainstream ones, I'm not even talking about the Tumblrinas or whatever they're called these days.)

... your fallacious appeal to longevity of the movement notwithstanding, this is the exact attitude that is alienating/off-putting -- "why everyone can't get on-board" the entire platform of what constitutes progressivism, which by definition is always advancing (and it has to be the entire thing, otherwise it doesn't count)? Give me a break.
