Thank you so much for reading and commenting on my blog. There indeed should be religious freedom which is found in these countries. Saudi Arabia is like head quarter for all the Muslims, as headquarters are having significance every where similarly there are some rules for maintaining the importance of these places. Maybe that's why you find it enforcing, else I have seen people living from different ethnic backgrounds in Saudi Arabia. For non Muslims all of the three countries I mentioned are undoubtedly offering religious freedom .
