what do we do to keep us safe?

Don't let Third World foreigners from Africa and Muslim countries into America. This won't happen because Barack Obama is a Marxist, hardcore anti-colonialist and anti-imperialist, and also hates white people. He wants to carry out his "fundamental transformation" of America and to anyone who pays any attention to our country and the news, he has been carrying it out since he was elected. He allows illegal Hispanics to flood and invade our country unchecked because he wants to overrun the dying out white European-American population with brown people (like himself) from all over the world. He allows hundreds of thousands of millions of Muslims to come to America despite the fact that Islam has no fine and accepted historical place in The West and that it is antithetical to our secular and/or Christian European nations in Europe and North America. He doesn't care because he is the ultimate Muslim sympathizer. He imports Third World Africans by the thousands every year to America despite the fact that we already have nearly 30 million African-Americans in this country. He wants more because he is African and because he wants to minoritize white people in America with brown people from all over the world. He has succeeded because by 2043, America's whites will be a minority in the very nation that they managed to found and then build up into a superpower by the mid-20th century. How do we keep us safe? Don't let foreigners from Third World countries and from lands with extremists who hate us into America. They have ZERO right to be here and to be citizens. There is NOTHING in the Constitution that guarantees any foreigner the right to citizenship in America. The Congress in conjunction with the President decides where immigrants come from, when they can come, and how many can come. Trump is right. Moratorium on all Muslim immigration and I would say on all immigration from non-European countries until we have a serious national debate about where our country is headed. You know how I know that this is being read by 18 year-old Bernie "Bolshevik" Sanders voters? Because you're all confused and/or ornery about it and because you weren't alive half-a-century ago when this sort of thinking was mainstream and the norm. America is a white European nation. It may not have an official religion but if it did, that religion should be either Christian or Judeo-Christian in nature, not Muslim, or some backwards African voodoo religion being brought over here by Third Worlders these days. I'm standing up for a white European and white Christian America like I have a right to do. Want to keep us safe? Have a homogenous America instead of a Third World Balkanized hellhole and dystopian nightmare like Barack Hussein Obama wants so badly.
