Nobody is going to question some forty year olds about their music tees to see if they are actually into the music. It's not like you are kids born twenty years after the band split up and wearing your tee's to be cool.
Going off those posts the only gatekeepers and ones being judgemental are you two. All this after some fellow black metal fans who organise a long running festival were nice enough to offer Nordy a flyer and show an interest.
As for Justin's Ulver experience that's not gatekeeping by the checkout guy who clearly knew of Ulver by referring to an album title, that's simply Justin, in his own words, being extremely lame.
Out shirts are our culture, our reference point, our calling cards if you like, not a test of credibility. They are our colourful plummage, if we were birds in the rain forests we'd be showing them off to other birds not hiding away when another came over and jumping back into our nests till they'd gone away in case they wanted to, you know, interact.
Okay, credibility lecture over.
