Because people are jealous. Or maybe because people hate Justin and see them like him so that be judgeful and automatically hate on them too. And maybe because of their bromances. I'm a Directioner since 2011, right after TXF I became one because I've learnt about them late. Anyways, whenever I use my 1D pencil case or bag, people make fun of me and bully me. I wish I knew why as well but these are my thoughts..
