> The second one was for specifically racist messages - i.e. breaching hate speech laws - not just being mean.

Can you provide a definition of "hate speech" which doesn't also apply to "mean words"?

Are you suggesting racist words are a special category of mean words or something? If so why?

Hate speech is a subcategory of mean words that needs to be legally prevented for a just society where people are equal. Racist words are only hate speech if they are uttered and used in a discriminatory manner. Since whatever group is targeted by hate speech is the only group that can be harmed by the hate speech, they should be handled differently in the eyes of the law to ensure no one group is excessively discriminated against
