Oh, it's "talk about posers" time. This brings me back.
I'm not that old. I'm 32. I got into Nirvana after Kurt Cobain died and I wasn't even that into Nirvana, to be fair. Mostly, my friends were grunge and I was like 'yeah, this is cool'. My favorite Nirvana album is Incesticide, because my tastes align more with ska and, more popularly, punk, often of the California hardcore-punk style. I listened to the 90s punk quartet--that's Green Day, The Offspring, Rancid, and NOFX--and was quite happy with that. But I also was down with so many other bands. I've still to meet another person who owns the entire Screeching Weasel discography, including their Ramones cover album (in which they do Ramones covers with such a squeaky voice, it's great) on recorded cassette tapes. Yes. You read right.
I used to call people posers. I never really was a gatekeeper--for some reason i found the right punker community in my city where, when someone didn't know something, we'd--sometimes just a teeny tiny bit condescendingly--learn them about it. We had a dude we called Biblia ("Bible") because he was literally just a repository of punk knowledge. If there was a punk band who had an album and it had been bootlegged internationally, he had listened to it, categorized it, memorized it, and could name all the songs. He was the BEST of us, and his knowledge didn't make him the best of us--his lack of judgment did. When any of us made some mistake--claimed something, whatever--about anything remotely punk, he would just correct it. No 'Actually...' or 'God you guys are dumb, what really happened was...' or 'No, posers, ...' He would just state the fact, and move on. If you didn't care, you didn't care; and he didn't stop passing you the joint or the beer because of it. His measurement of what made you a fan wasn't whether you knew as much as him or even whether you cared about it--it was whether you enjoyed it. That dude was awesome. He died about ten years back. His funeral was punk as fuck.
Further, talking about posers, I know a ton of people who can name every Nirvana song, own every album, know all the lyrics, and still fail to see the forest for the trees when it comes to the messages that Cobain was expressing. People who treat others like fucking crap, people who have told others to "killy ourself", pressured them to drug use, used them, abused them, turned around and blamed Courtney Love for driving Cobain to suicide and then actually gaslit their S.O., and many, many other things that, if you actually listen to Nirvana, consider their social commentary, you would know are pretty fucking incongruent with the band's general message.
Those people are posers. The person who likes the baby and the words 'Nirvana' and 'Nevermind' or got gifted the t-shirt, or whatever? Not a poser. Just a person.
I don't know.
I like to think that if Cobain were alive now, and someone said "You should only be able to wear Nirvana t-shirts if you can name some of their songs" near him, they would be the immediate recipient of his saliva smacking their forehead.
How dare you tell people how to live their lives when they aren't doing shit to you? And how fucking lame is it to have to insult people for shit that is innocuous as fuck?
Have some perspective.
At least get mad at actual idiots, like people who wear Che Guevara t-shirts but can't even revolt against their parents. "Viva la revoluci贸n, mom, now can you send me my allowance, my Twinky supply is low". Fuck.
