Jesus, man. It's the thought that fucking counts. Are you really going to give people shit for organizing an event that benefits the survivors of a terrible tragedy? You're probably not going to go to this unless you like the kind of music these bands play, in which case, you've probably heard of bands with names much worse than these. If the whole trigger thing is that
bad for you, you're may as well quit listening to extreme music altogether.
Besides, I'm pretty sure that if this had bands like Death Angel, Overkill, Warbringer, Megadeth and Anthrax, you wouldn't be complaining, although those names are just as if not more so disturbing as the ones featured on this bill.
What a fucking pussy. Don't say stupid shit if you're not ready to defend it.
