If the US borders are erased, all America (Anglo and Latin) get merged and all the world gets invited in, will the Americas and world become like USA or will USA become like the rest?
So what?
Don't you see: If America is more a place then an idea, what difference does it make if they become merged or not? His entire arguement is based on the premise that America is somehow being 'perverted' by too much immigration, yet, if America is only a place, and not an idea, what exactly does it pervert?
It's not that I favor completely unrestricted immigration, but his arguement is illogical.
