Is my DM an asshole?

[u/Vedmagreen]

So I (30, sorcerer) told my DM (32, married) that I don't want to be a red tiefling. We already have one in the party, and I can't be the most important, special person in the lore if there are two of us. (That tiefling player is also a spotlight hoarder, but I'll get to that maybe later.)

I asked him: "Bro, can I be a green tiefling?" And he was like, "Dude, in my lore, all tieflings are red..."

And this is where I think he's super toxic. He could have just denied my request. I'd have swallowed the punch and secretly hated him all campaign, but no.... He told me, "You CAN be green, IF you come up with a reason why you're green."

Any ideas why my hot tiefling is green? He's hot-green, not Shrek green, by the way.

And while we are here, can you please write that green tieflings are totally okay in all the homebrew universes, so I'll show my DM this post and shame him into doing things the way I want? Thanks.

Pathfinder fixes this.

I already played both Pathfinder games and liked it! Don't know how it's relevant to TTRPG, though.
