It's totally different in a place like the US. We have more land than we could reasonably populate and plenty of natural resources. We could absorb enormous numbers of people and we would be better off for it.
No....we have room for people that WANT to assimilate into the US, learn the common language, and believe in what the US stands for....not to come in and tear it down and form into something else.
Wanting to come here and start sharia law....that's a hard NO.
We do not want people coming here that on a basic level disagree with what the US stands for, what the US constitution was set up for, and do not want people that do not want to become a US citizen and embracing what we stand for.....we do not want people coming into the US and staying, that hold loyalty and allegiance to foreign countries and entities over the good will and preservation of the USA.
No....diversity when it includes anti-American feelings and politics are NOT something that is welcome here.
NO...not everyone is welcome nor should they be.
