I'm part of a lot of them Male and Female groups lol

I wonder why some fans hate certain groups. I was talking with a fan (I won't mention the fandom) but she HATED SNSD with a passion. I asked her why and she said they are just plastics trying to seduce guys and her oppas.....

sigh~ Can't we all get along? even if you don't like a certain group you don't have to bash them T___T
