I know some Jewish Republicans...but I think that Black conservatives and moderats Muslims are just a myth.
There are Black Conservatives. I have met many of them. They just don't often get into the news streams for people to be familiar with them.
The media routinely edits them out because they threaten the Liberal monolith.
A Muslim who is "moderate" is a heretic to his faith. When called upon it, they will reaffirm their faith by becoming vicious. If they do not, they will be killed by the members of their faith who are true to it.
I know black conservatives.
