I reverted to the word, “negro” about 9 years ago.
Now, only the term Caucasian is not considered racist. Technically, Mongoloid should be okay as there IS a country named Mongolia. However, anyone of East Asian extraction would be offended if called a Mongoloid.
It’s funny you mention that because I also reverted to calling white people Caucasian at that time to make sure I stayed equal in my use of the term.
