For the Muslims — it is an America subservient to Sharia law.
For the Mexicans — it is an America which is reduces to a vassal stet to Mexico.
For the Chinese - it is an America where they can make money and stay separate from the general population(same as everywhere else they go in the world)
The US Constitution is antithetical to Islam. Send them back. In fact a wall should be put up around Syria and let the Islmic folks in there develop their own utopia.
