Seems like the point is "If our flag (culture,laws,social structure, etc.) bothers you, sign up for a ride on the next thing smokin!" I fail to see any duality in a message like that, and whole heartedly approve the message it's sending.

It's kinda like a conversation I had with a cuppla Yankees I overheard bitchin about bein in Texas some years back. I told 'em both that I didn't personally know any one who had invited them here, nor did I feel as if anyones feelings would be hurt if they were to leave, so if they didn like it here, why not tear their asses back to where they came from so we could all be more pleased with ourselves, or ... STFU! That same exact logic seems to apply nicely in this instance too
