That pitch could use some work, and I don't find that player as particularly realistic in this situation. So I can't really answer. It's an absurd reaction, and if it isn't that absurd from that player, why the heck did the GM think this idea was going to fly?
You've never found out the hard way a player has a particular--shall we say--thing about something all of a sudden without warning? You're a lucky person. I've found out players I've played with for decades hate a particular thing without getting the faintest hint of it previously, and had a player suddenly absolutely fixate on doing something I'd never have assumed they'd care about.
It is a weird scenario. If I was confronted with this, I would just be, alright, Elves are all the knock-off Bravosi. You are Dravosi now, you came to this strange land which is home to so very few of your kind.
And that's a really damn good way for the campaign to suddenly be all about that particular character even if not intended.
