Commonwealth Games - Why?

Ok, what I don't get is this. The Commonwealth Games start this month in Glasgow. According to Stephen Fry, of the 42 countries that have anti-homosexual laws on their statute books, 21 of them are members of the Commonwealth. We (Britain) are supposed to be opposed to countries that have anti- homosexual laws on their statute books (Uganda and Kenya are examples). Yet we are not boycotting the Commonwealth Games. Why not? We should be! I personally am boycotting the Commonwealth Games and will not be watching any of it on TV. Can others join me in boycotting the Commonwealth Games, to show those countries that are opposed to homosexuality what we think of them?
