Quote:can Mohammed ever be a Christian name?
Not that I know of.
However, it might be tangentially relevant that our Muslim compatriots tend to choose the names for their children from a much narrower scope. Much like the white Dutch used to (my father is called Herman Jan, his father Jan Harmen, his grandfather Harmen Jan etc), they mostly choose names from a relatively smaller pool of traditional or family names.
I don't really know about Belgium, but in Holland this would contrast with the sometimes positively florid array of names that white (or black) Dutch parents give their children - and would make single 'Muslim' names quickly rise to the top of the charts.
Like I said, tangentially relevant. Percentage of newly born children to Muslim parents on the totality of newly born children would be a more obvious reference point than children's
names.
