Congratulations, I think they're silly as well.
And that's coming from a guy who was a hardcore metalhead for years. I'm not judging whether it's appropriate or not, I'm saying that I think all that stuff is silly. It looks silly, it usually has no function (biker helmets notwithstanding), and half the time it's just plain uncomfortable. Just look at goths sweltering in the midday sun. I'm
way past caring for people displaying their preferences through fashion statements like that. I'm much more inclined to respect people with practical fashion choices instead.
