Like many people above me have said: it depends. I personally don't get involved in the toxic part of the community and I rarely encouter problems with other fans. Even on Twitter (only had one argument and it wasn't even about Kpop. And they only replied to me once before they gave up). I do see a lot of other people get into arguments or fights though. Or I hear from other peoplr that someone said something hurtful and/or disrespectful. So in general I would say no.
