It is actually a common name in parts of Europe though. 🤔 At least, the rankings depend on if you include all the spelling variants (Muhammad, Mohammed, Mohamed, Mahammad, Mahomed, etc) as the same name or separate names. Bit like if you count Catherine, Katherine, Cathryn, Katie, Kathy, Cat, Kat, etc, as a single name or names in their own right.
Anyway, who's claiming he's a white nationalist?
