I agree that the importation of "world citizens" to suck off the host body is a big problem, but I don't see these "world citizens" as necessarily an impediment to Americans fighting against "gay marriage." Why would a recently arrived immigrant be a defender of "gay marriage", unless perhaps he himself is a homosexual and wishes to take advantage of this newly found "right"? "Gay marriage" isn't a part of the experience of the vast majority recent immigrants or invaders.
I 100% include corrupted natives in my definition of “world citizens”.
If anything, they’re worst than the imports; they knowingly and willingly soil their country of origin.
