"You move to a new place, you need to adapt."

Right. Those guys have been in the country for centuries. It's not a "new place". You're just as bigoted as Rand. And "we're not the thought police"? Right. You're demanding assimilation, that makes you indeed the thought police. Downright fascist, in fact.

But how kind of you to "allow" them to keep a bit of their culture. Mighty nice, Mr. Jackboot. THAT is right out of the playbook of fascists and supremacists.
