that list is – alltought made by a historian – subjective to this man’s vision only. Other historians would of think otherwise.
Secondly being in the list as one of the greatest influences doen’t neccerarly make you ‘great’ in the good sence... their are names among it like Ghenghis Kahn, Adolf Hitler, Hernando Cortez, Augustus Caesar,... and numerous other conquerers who weren’t exactly saints... meaning that the list doesn’t make distinguished between good and bad influences. It only sees ‘influence’.
Next to that muhammed is only praised for his earthly conquering and manipulation of the masses...
It's the earthly kingdom Jesus rejected when Satan offered it to him wich muhammed gladly accepted in return for his soul.
You may be proud of your mass murderer.
