Wiliki, I take it you've never lived in CA.  With the threat of terrorism, where the goal is incite terror in the West, an open border would be self destructive. How many should we take in? Unlimited numbers? Do they all receive food stamps, medical care and education. How about housing? Can we take in 20 million? How about 50, 75, or 100 million? Have you really thought this through? True, they would all vote Democrat, but what will the Democrats be controlling?  How many immigrants should Hawaii take in? With open borders, I'm sure a lot of people from Central America, China,  Iraq, Syria, in fact , all over the world, would love to live in Hawaii.  Are you ready for that?  Or would you stipulate that the rules for entering Hawaii would be different.  After all, there isn't a homeless issue in Hawaii. There's plenty of room for immigrants. Maybe we should focus on  Muslims. They have on average over 8 kids per couple, which should help solve our declining population, right?
