What is religious racism?
That is a very good question. Race is defined as a class or kind of people unified by community of interests, habits, or characteristics eg the English who are made up of Pakistanis, Chinese, Indians, Danish etc. Therefore the Jews and Muslims could be considered a race at the same time as being a religious group. Anyone who discriminates against such a group on religious grounds eg forbidding marriage due to religious differences could be said to be committing religious racism, I think. I am sure many people will disagree. We will soon find out.
