Muhammad was white? Since when? I would call him an Arab, and in the 7th century I don’t know if any of them could be called “white”.
Long long ago when I attended primary school, we were taught that there were three races - caucasian, negro, and mongoloid. All people were cast into one of those three groups. The near east peoples were considered caucasians. A lot has changed sin the 1950's.
negroid, caucasoid, mongoloid....the races. If Mohammed wasn't a caucasoid....what was he??
