I don't think "open" borders is the right way to describe those who believe in free trade.
Open borders implies there is no control about what or who comes across a border.
Free trade is compatible with security checks for both goods and people coming across, and can designate certain goods and certain people as illegal for entry.
Open borders does not describe my position at all.
The man this forum worships on kneepads believes in open borders. Since he is the head of the Republican party, and I assume you consider yourself a Republican, that makes you in favor of a no border policy. BTW, in '08 the borders will be erased by general agreement. There was a summit at the Taxes ranch, and people will be able to cross with the proper sticker.
