Typically simplistic, and entirely inaccurate Prager take on a very important issue.
No nation can survive without a secure border. Race has nothing to do with it.
Even those nations the left loves to trot out to use in comparison to us, to show how bad we are, have secure borders and strictly controlled immigration policies. The Nordic countries, Australia, etc., limit immigration. When I was visiting Sweden and Norway, I asked people about their country's immigration policies. Every single one of them said things to the effect that the numbers had to be limited, and the immigrants needed to assimilate into the country's culture. These are people living in very nearly socialist countries saying common sense things. I kept thinking that if those words had come out of Trump's mouth, simpletons would be accusing him of hating brown people... brown people bad.
In even worse news for you and those who think like you, in typical libtard fashion, your demotard leaders have bungled this issue entirely. They were simply too ignorant to realize that many illegals who come from countries with strong catholic populations, with strong religious and family values, might just find that they feel far more comfortable with the republican party than the democrat party. Leftard incompetence strikes again!
So Prager, those who advocate for open borders are simply on the wrong side of this issue for a whole host of reasons. And for them, it is all about race, which makes them the racists.
