Are terms like mulatto and quadroon racist?

You would be wrong

https://en.m.wikipedia.org/wiki/Mulatto

Wait, are we reading the same article?

The term may derive from mula (old Galician-Portuguese, from the Latin mūlus), meaning mule, the hybrid offspring of a horse and a donkey

The accuracy of Wikipedia not withstanding, the first suggestion of origin of the word in your link is almost verbatim what the quoted poster suggested. So, how is he wrong? Do you know more than your own source?

I thought he meant from the English word mule. But I guess that is not what he meant.
