That whole thing about Baekhyun's brother's wedding is fake. Some anti started that rumor up to cause distress in the international fandom. Yes, some of EXO's fans are crazy, but more often than not now, a lot of the stuff that comes up like this is actually because of trolls/anti's. Sad truth that is, especially since a lot of people just peg EXO's fandom as terrible, when yeah, it does have it's bad moments, but some moments are created by anti's/trolls and because of that, EXO is blamed even worse. It's a terrible thing because there are a lot of great people in the EXO fandom and because of the few and anti's, people think EXO is automatically a terrible fandom when that's not always the case.

Try watching EXO-M instead of K or just EXO, because M actually has more stage presence and owns the stage more than K does. M usually always has better performances than K, so check a few of their lives and you'll know that they are actually pretty good.

And you can't just say other groups deserve more popularity than EXO, because EXO does work hard and part of it is on the company and how they do their PR to have their groups gain that status. SM just happens to be a genius at their PR and after years of cultivating those skills, it's no wonder how EXO became big. It's just like YG, they can literally do the same thing as SM and their groups would get big as well without too much prompting. Both companies have been around for years or so, and when you've been around that long and have popular groups, of course their groups are going to get popular really fast.

Don't point fingers at all EXO fans.
Those are Sasaengs almost all KPOP groups have them (Mostly male groups)
That's like pointing at America and saying that everyone there is a movie star..........
