Why do I think that those communities will cave?
I hope you prove me wrong.
You might be right, they are probably about 50% or more Hispanic(and thats just the legal ones) and a huge amount of integration has gone on there, in Dodge City( my old home town) there are almost no nightclubs for English speakers so everybody pretty much goes to 'latino' clubs, and there entire economies are pretty much tied to nothing but the meatpacking inductries.
