I don't see Marie150 as having the government forcibly make them leave.
I believe the statement "If you can't stand the heat, get out of the kitchen" applies here instead.
Translation in this instance:
If you hate America so much, why are you staying?
This is not, "We will kill your or incarcerate you if you do not bow to our laws."
...which does in fact sound a bit like many of Obama's directives, come to think of it.
