Thankfully, despite being a metal fan, I’ve never listened to enough Metallica for that song to get stuck in my head, and I probably never will. Fuck Metallica for supporting DMCA. I’ve heard they’ve been kinda coming around on it, but what a dick move. The way it’s set up tends to be ineffective or damaging to small artists.
Hell, what’s up with the big thrash metal bands? Like, Metallica helped get DMCA passed. Megadeth has Dave Mustane, a racist, homophobic, conspiracy-theorist and born-again Christian frontman. Slayer has an supposedly rabidly antitheist frontman. Anthrax is the only one where I don’t recall reading anything recent (within the last 10yrs or so) about the band members being shitty people.
Because I don’t even know where to start. The biggest part, I suppose, is that if you give them a space like this, it normalizes the movement. People stop feeling like there is something wrong with disliking the LGBT community, the movement grows as it is no longer stigmatized, and LGBT rights backslide.
Furthermore, holding a “hetero pride” festival during pride month is inherently bigoted as well. Pride month exists because straight people wouldn’t let gay people express themselves otherwise. Your idea isn’t totally unlike the idea of letting klansmen openly hold festivals during Black History month so they stop harassing black people.
