We may define "great" differently, but I'm sure sensible people recognize what Islam is contributing to the West.
What do you mean? Muslims contribute many things to everyday life in western countries, such as honor killings, wife beating, polygamy, welfare fraud, raping non-Muslim girls, barbaric Sharia law, and did anyone mention... blowing everyone up?
How about we see some Christian book stores open up in Saudi Arabia, and then maybe we’ll talk.
