You answered no questions I posed and the one attempt you made is simply wrong. The COnstitution is silent on immigration. Immigration and naturalization are not synonomous. Immigration regulation is a power that accrues to all sovereign entitities and in America we have a country and states that make up that country. All have the power to exclude the those they deem excludable so long as the states do not run afoul of specific laws enacted by Congress. I'm still waiting for you to post one of those.
And quit whining for peats sake. You got sarcasm because you gave sarcasm. Grow up.
PS: Are you a penumbra guy? Because every time the majority used the word "field" I was seeing penumbra.
