In response to the original question, I have met several people who believe differently than I do, but are still Christians. I even have a friend who got an abortion over thirty years ago and believes other women should have the right to do so. I know that is incomprehensible to many. I was shocked when she told me.
Bottom line, she is a Democrat and a Christian.
I also worked for many years with other Christians who were homosexuals and Democrat.
I even heard of a Baptist preacher who was a Democrat.
I've learned to respect people who have beliefs different than mine. We don't have to be besties, but I have learned to respect them.
Follow up question: could you be a friend to a democrat, a homosexual and/or someone who had an abortion?
