I cannot think of any liberals that I could be friends with. Most of the liberals that I have met have a mean streak in them. When I ask them a question about economics and they cannot answer the question, they call me an a**hole. I have liberal relatives and co-workers, but I am stuck with them.
I have liberal acquaintances and co-workers, but no liberal friends. I have purposefully lost touch with old friends who are now America-hating commies. I don't care to know them.
