Now that argument doesn't make sense. You are comparing a genre with a tv station.

It's like saying "Because they don't show splatter and horror movies on Disney TV, they don't exist".

Sure, 18+ comics might be less popular than their manga/anime equivalent, but that doesn't negate their existance.
