This "keanu" guy is a liar. Why would Mohamed speak in a foreign language except for English racial slurs cataloguing each person as they walked in the store? It's pure BS and it is being dealt with.
Please do not pretend to tell us that you have never heard, let's say, a commercial in Mexican where they come to a word or words that have no translation into their native language?
German, Italian, Spanish (i.e., Castilian) French, etc. I listen to jazz over a variety of internet stations in foreign countries and this happens all the time. Other than Keanu telling us (and we have no reason not to believe him other than perhaps personal bias against him) I have no proof that Makkawy did this. But it is likely he could have because I hear it frequently on the radio and in the world around me.
People can be jerks. Even people of "color". Its just that more often than not, they get a free pass from society.
It's entirely possible that Makkawy is a great bodybuilder but an average person.
