In the case of BC I don't think @CiciBass needs to be worried, especially given some of the rubbish that gets talked on here!
Elsewhere, particularly on FB, I've found that while a lot is as you describe, some of the "delete if not allowed" crowd overlaps with the "I'm just saying" crowd where they're just daring people to disagree with them so they can cry freedom of speech, cancel culture, or some other bollocks.
