Well, now that I think about it...................................
I have seen more toxic western stans than well, kpop stans.
To be honest, this whole "kpop stans are so toxic" thing is biased. Not every kpop stan is toxic and a lot of other fandoms are toxic too.
I mean, you have fandoms that made a girl commit suicide because they didn't like her artwork.
In the end, every group has bad apples.
Hating on all parts of a specific group of people just because they are "toxic" is just stupid and immature.
