whats with all the hating?

it really confuses me how peopel just hate eachother bc of what clothes they wear. or even just the vibe they give off. 

for example, me and my friends just be sitting at the park, minding out own buisness. and all of the sudden were surrounded by teenage boys on biks/fatbikes. they start filming us and barking at us. just what goes trough their minds to do that? just bc my pants are black and my shirt has a band name on it you act like this? or even when i go out and im just wearing bleu jeans and a jacket people still bark at me. just what ges trought their heads? 

antoher thing with the barking, what are you? a dog? you make fun of me but youre there standing there barking at some teen? like your barking at me, you want to be my dog? it makes no sense

and this was just about the clothing. when i try and talk about an intrest of mine, people will automaticly assume that its something super weird, even when its a populair media. and they start to hate me bc of that interest? like if you start hating on me for this kind of stuff, what do YOU like. not what do your friends like, or what is populair rn. what doe you like?
