Muslims have contributed nothing at all to America. Obama never did call Colleen Hufford's family after she was beheaded by that Muslim but Obama did sent six people to the beheader's mosque to congratulate them on their good works- OBAMA REALLY DID DO THIS. Obama is a Shiite Muslim and does in fact hate America and Americans. Daily he rubs this in our faces thru his aggressive violent racism, his support of the Muslim Brotherhood, his travels to Islamic nations to kiss everyone's hands. Obama is right now conspiring with our enemy Iran to complete their weapon program so that Iran can destroy Israel and then bomb America... as Iran has publically stated a hundred times. Obama is a TRAITOR.
