He's almost certainly exposed to more cultures, though you are right: he could be extremely bigoted and xenophobic. It's just less likely, even if marginally.

"The bourgeoisie are probably smarter, better people than the proletariat"

This isn’t about bourgeoise vs proletariat. It’s about a completely asinine allegory that elides tons of real world context in order to push the ridiculous narrative that the simple country folk know something the rest don’t.

No, it's about you calling someone a xenophobic bigot because they're a country bumpkin and assuming someone else is probably not a bigot because they're a city person.

Side note, you do know the definitions of the words "xenophobic" and "bigot" are right?
