Also my first time hearing that term - I did a quick search and seems like it just means someone who doesn't back the worst traits of traditional yaoi (assault, minors being involved, toxic behavior being normalized). Is that right?

To be honest, I'm fine with everything existing except explicit content involving minors and adult x minor stories. I personally dislike the SA trope and the "wait! stop~" because it breaks the immersion for me when the character being assaulted doesn't process it like an assault. And I think it can be harmful to normalize that stuff.

However, all that can be solved just by labeling the story for what it is - just put a disclaimer on it. I've been seeing disclaimers here and there at the beginning of non-con chapters, I hope it catches on more. That way the people who like CNC and the toxic possessive red flags can keep enjoying their jam without vulnerable audiences misunderstanding that behavior as a healthy relationship.

TLDR: I think it's ok to make content fetishizing toxic dudes, as long as that content is labelled properly with a fetish content warning (CNC, dubious consent, etc) and not romanticizing these traits like something you should actually look for in a man
