Yeah. Sometimes I see private Facebook groups by otherwise smart people, where one rule is something like "racism of any kind is forbidden". As if the addition of "of any kind" made the concept of racism any less vague.
I think that it might make expectations about moderators' interpretations less vague.
That still seems as if it adds some useful information. It's informing people ahead of time that moderators will probably not interpret "racism" in the narrowest possible sense, or likely even in a medium grey-area sense, but rather in a broad sense.
