ok it's satire and you've clearly missed the joke. but if you want to get into it: the article intentionally points out that only white, cis, men attended. the punk scene is NOTORIOUSLY terrible for women, non-binary/non-gender conforming folx, and non straight people. that's not to say that punk isn't popular with that demographic. that's to say that spaces full of white cis men push others out with their behavior, so those people create their own spaces. just because you declare a space "safe" and non discriminatory, that doesn't make it so. that's what the article is lampooning. all these hypothetical dudes have said this place is now safe! but it doesn't matter because only cis white dudes showed up, broadcasting that same unsafe message.
