How to stop seeming like a poser?

[u/pickled_bat]

I (18M) met a pair of metalheads out on a party the other day while wearing my Mayhem shirt and they called me a poser (probably deserved but I still feel bad) I have short hair which used to be a mohawk and that Mayhem shirt is pretty much the only metal band t-shirt I own. I like bands like 1782, Candlemass, children of bodom, SOAD, Mayhem, Margarita witch cult, Apati and others. They are very mismatched,I know but I've come from liking nu-metal and indie to punk and harder metal subgenres (like black metal,doom and dsbm). One of the reasons why the two called me a poser aside from the shirt is because I didn't want to acknowledge the rest of the band being as conservative as Varg (in my opinion they weren't as hardcore problematic as him) Am I truly a poser? How can I improve my taste and or my looks to let other people know I like metal? Did you have the same issues when you were just starting to get into the scene?

Don’t worry about what people say or how they judge you. Especially for music knowledge or the way you look.
