Anyone who subscribes to the Democratic Party line of thinking is automatically disqualified as a "Christian" in many churches. I think it may fall on the definition of the word "Christian". A follower of Christ would not accept abortion, partial birth abortion, homosexual marriages or any other item of the liberal agenda.
I had a friend who passed away a few years ago. He was a died inteh wool new deal dem. He served in WW2, got out joined a union and worked in the plants his whole life. He was even a union shop steward. He voted in his first election 1940 and his last 1994. After that he could no longer stomach the rat party. He told me this once, "Son, if your family does not make at least $250K you have no business voting republican, but now days if you are a Christian you have no business voting democrat either."
Many of them don't, but are still more liberal in the "social justice" area. I consider them misguided, but I can't reject their position as brother and sister in Christ because I don't agree with them. I have also known Christians who DO believe in some of the things you list. They believed them in an early part of their walk with the Lord and later came to understand that their beliefs were against those taught in the Bible. Fortunately, God is more patient with His children than most of us are.
