Why is there so much anxiety around being a poser?

Isn't that what it's all about? Why does it matter so much? Why can't people just be happy? Why are some people so gatekeepy? None of it makes any sense to me.

I just wanna look cool and listen to fun music, why should I worry about not being "scene enough"? No, I don't have typically scene hair. I like my loose, blonde plaits. Who gives a fuck?
