That definition seems to imply that "speech intended to degrade, intimidate, or incite violence or prejudicial action against a person or group of people" is not "hate speech" if the person or group involved doesn't occur in that list. Or does that peculiar term "any other distinction-liability" mean that the list is infinitely extensible, and that Morris Dancers, smokers and buskers are covered.

In which case why not just define "hate speech" as "speech intended to degrade, intimidate, or incite violence or prejudicial action against a person or group of people"?
