Well maybe you should have been more specific about your definition of what constitutes shit-posting, because from what I read in your OP, the connotation I got was that (and this is corroborated from personal experience back when I was a YouTube Premium member; I no longer am) the populist definition of 'shitposting' is posting content that intentionally denigrates an opposing ideology or denigrating a person (or meme) based on some inherent, inalterable trait, such as skin, hair, or eye color.
I've always had it against shitposting based on the above definition and more so nowadays due to the COVID hate crimes specifically waged against my ethnic community. Anyways... everyone has their own definition of some things; one man's 'shitposting' is another man's 'activism', and so, "do whatever floats your boat"!
