>He glosses over Muslim history and al-Andalus with a "the Muslims were driven out of Spain" like Spain itself wasn't Muslim for almost 800 years.
Yes, the colonists were driven out. We should celebrate any time in history native and indigenous people defeat their colonizers and reclaim their indigenous lands.
The descendants of the Muslim colonists were defeated by the descendants of the Roman colonists, fighting under the banner of the Roman Church, and not by the native and indigenous people of the Iberian peninsula.
The native and indigenous people of the Iberian peninsula would be the Celtic, Iberian, Celtiberian and Aquitanian tribes conquered, colonized, and assimilated by the Roman Republic. The land was later occupied by the Germanic peoples before entering Muslim rule.
