Words can't be racist; people are.
That must be why dictionaries describe such words as offensive, racist, derogatory, pejorative, etc.
Words exist to communicate thoughts, ideas, attitudes, etc.
When someone uses such offensive, racist, pejorative and derogatory words they communicate racist intentions.
When sxturbo uses such a word it demonstrates his racist attitude.
When he initially denies his racism, and tries to hide his obvious intention, it demonstrates his lack of understanding, and his dishonesty.
When he claims to not care whether he is considered racist or not, because he refused to accept his racist intent, then he is racist and disingenuous for using such offensive, derogatory, pejorative racist words, and trying to deny it.
When he seeks support from others for his actions, he is promoting his racist attitude.
And I notice that some do support his racist attitude, you, and Lower for starters.
