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.
That's when the Ladino speaking Jews also arrived.
Conversions were numerous even when not coerced.
We are discussing a VERY LONG period of time in a unique civilization.
The Islamicization of Classical Spain was quite thorough until the Reconquista really got going, and that took several hundred years.
Your reference to "Medieval" is not informative since this history runs from 711AD, which is clearly "Dark Ages", or the earliest part of the Medieval period, and does not end until 1492. That's roughly 781 years ~ a coon's age fur shur. Conditions during the latter part of that period in Spain were far different than conditions during the earlier part.
