Muslims do not pray to Mecca they pray toward it. Spare me!
I have worked in temples where I cover my head and respect where I am. (and that is in Canada)
If I am in the Muslim world I follow their customs and beliefs, and believe me you will find out the hard way as many have in some countries if you do not!
The British are also leaving to places like Canada and Australia where there is some space and feel less crowded by immigrants.
