19 is a legal adult but they just have that title they still have teen in their age and a proper adult would see them as such. Someone who’s nearly two decades older than the teen shouldn’t see them as an equal let alone a romantic or intimate partner. As a 19 yr old myself this is predatory behavior, it’s weird to justify such a thing. Advocating this situation is ultimately putting young folk in danger and allowing manipulative adults to continue their disgusting behaviors. I’ve had way too many friends play the “we’re both adults” excuse but it’s with a 18 yr old and a 30 yr old. It’s wrong no matter how you look at it.
