Things that shouldn't be normalized in any literature form?

Lately, I've been noticing a lot of controversial topics mentioned in media and literature forms. I do admit that it's a good way to raise awareness among these topics, but sometimes it just feels forced and is unfortunately utilized for readers.

For instance, I've been noticing BL's or MLM patronized by author's who showcase queer relationships the worst way possible. "Oh, it's for the character" Yeah, I ain't going to ignore that the ML committed domestic violence on the MC... then later on his behavior is excused because got some cliché 'traumatic background'. It's driving me crazy to the point I have been staying away from MLM literature for a while because of that.
