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 Amore one direction with all my cuore but people dont like them because there juding before knowing one direction there the y suck but they dont even know one direction i Amore one direction with all my heart

Because people have different Musica 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 Musica ever. Not hating, just expressing my opinion.
