"if i hate someone i don’t even read their post"

Why the fuck do people waste their time to hate on someone they don't like nor do they know? If you see a post on an artist you don't like, why the fuck would you click it? People kill me with that. They be doin the same thing on mediatakeout talkin bout "I'm so tired of her." or "she's getting old". In their heads it should be "ooh! I see that this post is about 'Rihanna'. I'm NOT gonna click it". Why is it the opposite?
