What is your problem? I mentioned the coastline first, then the Canadian border, and finally Alaska. I guess I could have mentioned Hawaii, too, but my point was long lost over your head.
Arguing with you is pointless when you can't even grasp the little points.
It would actually be easier to stop from coming by water. There has to be some point where this invasion stops - you seem to want to rollover and let the country be overrun by illegal aliens.
