Uh, in order to follow this line of convoluted thought, you must start with the premise that Moses was a Muslim (ignore the fact that Muslims did not come to be for thousands of years – that’s not relevant). Ok, now that you have that straight, you must understand that Moses led Muslims out of Egypt – a country that is today Muslim – into what is today, Israel.
Oh, and did you know that David didn’t slay Goliath? It was actually Saul the Muslim. That would mean a Muslim killed a Philistine.
Are we expected to believe that? Muslims fighting Muslims?
