How do people not like one direction there population is huge so why not?

because there jealous ;)

This is the way I look at I 爱情 one direction with all my 心 but people dont like them because there juding before knowing one direction there the y suck but they dont even know one direction i 爱情 one direction with all my heart

Because people have different 音乐 tastes, not everyone is meant to like One Direction, we all forget that sometimes. They are good, but not the best thing to happen to 音乐 ever. Not hating, just expressing my opinion.
