I think thats exactly the point though. There is a perception that "left wing ideals" are represented in art and media and that this must end. This explains the executive order to defund NPR and PBS last week.

For decades gays were not allowed and their presence caused blowbacks. It was called free market, despite there being literal rules preventing their presence. Likewise, non whites or women in leading roles - they were not in them, because Hollywood was conservative business in this sense. It took a lot of advocacy for the change to happen.
Right wing hates them, most people just watch those movies and are not weirded out anymore about women having lead action role or whatever. And right wing hopes to revert it back.
