You need to broaden your horizons. Lots of romance books do have problematic elements, but so do lots of non-romance books. A vast number of romance books contain no explicit scenes at all (and some are as explicit as the most explicit hardcore porn).
If you’re cherry-picking your examples from TikTok, Wattpad, Reddit, or Instagram, of course you’re running into the most heightened examples. But there’s romance out there that’s healthy, gentle, non-explicit (some is so closed door there’s not even kissing), etc.
As far as concerning? Do I worry when I see people want relationships they see in books that aren’t healthy? Sure; but believe me, the modeling of healthy family and relationship dynamics is a) pretty poor in most books and b) have you actually talked to readers who read mostly genre romance? They read it for the same reasons people who read thrillers, horror, mystery, and sci-fi do. Heightened emotions, drama, an escape from real life. And most people are able to separate fantasy from reality.
I might personally prefer romances that embody healthy relationships, but I in no way think that means other people aren’t as capable of differentiating what’s in their books from what they should want in life as I am. Romance readers aren’t less intelligent than lit readers or fantasy readers.
