>You can't go using the wrong term because... BECAUSE YOU JUST CAN'T OKAY?!
Something to remember when browsing 4chan is that everyone here is autistic, and the faggots starting flamewars over inane shit are low functioning spastics. It's best not to interact with them, because they're incapable of reasoning when they're having a meltie.

GM and DM are just terms, nobody (normal) actually cares which one you use, they define the same fucking thing in subtext anyway.
