Hello, I Am The Old Death Metal Guy

I'm 32 and consider myself the Old Death Metal Guy.  This is a joke that originated from a chat group I was in that had people in their late teens through early 20s.  This one guy kept posting a bunch of modern slam bands (which I hate).  I eventually put him in his place with a "back in my day" speech.  Kid immediately dipped from the group.  I do feel bad for doing that but hey, sometimes you just gotta gatekeep.
