Racist Spanish and Hispanic Last names

One of the most important wars in world history and North African history is the reconquista, we still see it’s affects today.

Recently I saw a tweet that one of the most popular surnames means Muslim killer? This surprised me the surname in question is Matamoros this surname translates to Moor Slayer there is a city in Mexico with this name. My issue with this was how many likes the tweet reminder it’s been like 600 years since this war took place.
