I don't think so.
I had my belieber and directioner era. The fans were terrible with the guys' girlfriends. They still believe that Harry Styles and Louis Tomlinson are a couple. Nowadays I have a favorite band that is not as famous as these, but one of the band members got married and his wife posted a picture of the wedding. Some fans made Instagram take down her post, out of jealousy. And they really aren't that famous. The parasocial thing has gotten worse in kpop, but it's always been here. I even think it was western boybands that allowed things to be as they are today. And I know that the South Korean market is sick by itself, but what I mean is, if this has spread all over the world, it's because the ground has been prepared before. Things are progressively increasing and the only reason we don't have something like Army in the Western is because we don't have any big names like 1D was before. But really, directioners and Beliebers were crazy. I think the main difference is that, in addition to being able to date openly here, when they get girlfriends, only the girlfriend will get the hate. Like, they hate the girl, but they love the guy. In Korea, it is possible for his career to end just because of a relationship. So yes, there it is much, much worse.
That's just my point of view anyway
