Spanish aristocracy was full of moroccans

[Cristiano viejo]

Enlighten me then Cristiano viejito. History shows that the Visigothic kings dispossessed the native Ibero-Roman aristocracy of their lands to pay their army - Roman-style tax collection ceased to exist so that is how the chieftain paid his retinue for their services - and the protests and revolts of the nobility after Reccared's conversion to Catholicism clearly implies that at least the majority of the Spanish aristocrats in the 7th century were actively Arian.

Perhaps in the VII century, not in 1500s, etc, as the thread prays.

Explain why they were half north african even before the muslim invasion then

That does not imply "massive Punic colonization", as you claimed. In fact, if such massive colonization had existed we would have now hundreds and hundreds of Punic cemeteries in Spain, and we dont have it.
