Someone just asked a question about the difference between Creoles and Mulattos. A user commented some objection on grounds of racism, and the question disappeared within a few minutes of the post.
I don't know how the question was deleted, whether it was by the one who asked or in some other way. But it seems like a terror of words for races, and I just think that it is a pity. There was nothing offensive in the post. The words are now sort of old-fashioned, but still familiar enough to make curiosity about them unsurprising. Lots of people proudly identify as Creole, the word is used a lot especially in connection with food and language, and it's weird that we're not to consider the words precisely.
What would be wrong in allowing a discussion of the words?
