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.
Yes we need to patiently explain to them that they are wrong. Dead wrong.
I don't advocate a hate all liberals stance. It's counterproductive. You have to "grow" conservatives and you don't do that by knocking them over the head.
That said, our country is being attacked more and more everyday. Time is of the essence.
