This is a fine stance I'd be happy to work with. It's the unwillingness to compromise or give reasons that bothers me.If you can't deal with the DM's preferences being different from your own, you probably should find a different game.
Personally, I'm kinda a fan of compromise, if possible. No, you can't play a kenku or a tabaxi in my campaigns, because they're not on the campaign world. On the other hand, go ahead and write a backstory that adds stuff to my world; fill in a blank space for me.
And yes, I see that pretty often in the wild. Not in games I stay in for long, but it comes up.
