Many of these open borders advocates are not American citizens at all, but are visa overstayers and other forms of illegal illegal aliens. I wouldn't worry too much about them in general. They don't share our goal of defending American sovereignty, their goal is to shatter it.

I'll be glad to compare credentials with you. We could even make it very interesting. Would you want to put up some money on it? Who's been here the longest?
Do you talk the talk, or walk the walk?
