“Aside from 9/11—I really can’t think of another thing.”
Muslims contributed to the USA as follows:
1. Tested the Marines in the Halls of Tripoli.
2. Were the originators of the African slave trade
3. Caused the USA to build a professional Navy due to their piracy (see #1, related).
4. Have active prison “ministries” to run very effective criminal gangs that pull select blacks out of poverty, albeit generally to the detriment of their neighbors.
That’s about it.
Halls = Shores. Give me a break; I’m Israeli.
You missed one: Muslims invented the number ZERO, B.Hussein’s IQ.
