I read the article, and I am totally unable to see how universalism applies.
Those European countries are small. Traveling across Europe used to mean constant stops for border crossings. Imagine you were on the US east coast, and every small state you went through, you had to stop, present your ID, get checked, maybe a random search of your vehicle.
Besides, your stuff on only letting in Christian refugees seems to suggest they don't want their countries to become more Muslim. It is prejudice, but is it a bad thing? For a country to be overwhelmed with people with totally different values and a different religion, I cannot blame them for protecting their country. And that is simply not universalism by any definition!
