Roman Catholicism was "allowed" to be practiced by the peasants, of course, but that did not make Spain "Roman Catholic" by any means.
In those days Bishops were undoubtedly very polite to the political leadership elite in the Peninsula.
Shortly after the invasion and conquest the peasantry pretty universally became Moslem.
Incorrect. Maybe you should consult a student of medieval Spanish history (like you previously suggested), such as myself, before you go comically asserting Muslim propaganda.
