This is inaccurate, at least from my experience. Not on YT, not on Reddit and certainly not here. I think I see more levied at me for being a defender of TLJ than otherwise.Categorical BS. I've never ever seen a case where one of these "protected" works like Ghostbusters, Last Jedi, etc... is criticized in a scholarly way (think Red Letter Media's epic essay on Last Jedi) and the critics aren't still merely shrugged off as racist, misogynistic, bigots.
Some people insist that you're just not entitled to dislike a work if it features women or minorities. To dislike is to commit an Orwellian thought-crime.
