Why are choir kids jerks?

I'm just asking because I heard some of them at my school saying theater and band take no talent and they could do it in their sleep. I don't think they realize that all the arts are difficult, like in theater they aren't just memorizing lines but also they have to sing, dance, play a character and so on. And with band especially marching band is difficult as well because we need to all work together with insanely different instruments and keep time and hit notes right and memorize music JUST LIKE THEY DO. (Sorry, I just needed to vent)

Edit: Sorry for stereotyping, I didn't even notice I did it, and sorry, choir people, you have talent, and I think ocopela is great
