deviantART prohibits the submission of 'Hate Art' and 'Hate Propaganda', how is this defined?

Currently deviantART defines 'Hate Art' or 'Hate Propaganda' in a similar fashion as most national laws, only slightly modified to fit the internet environment upon which the site operates.

Submissions made to deviantART and statements made in the public areas of the site will be considered hate propaganda if a reviewing administrator judges that they meet the current definition in use at the administrative level.

The staff reserves the right to remove immediately and without warning any submission which advocates or promotes the genocide, killing, or destruction of an identifiable individual, race, religion, nationality, ethnic origin, sexual orientation, gender or disability or which promotes inflicting on the group conditions of life calculated to bring about its physical destruction. Submissions which incite or willfully promote hatred against an identifiable group or individual will be removed in a similar fashion without warning.

The staff also reserves the right to take administrative action against any individual who is found to be inciting or willfully promoting hatred as defined above through public statements made anywhere on the deviantART website. Administrative action may range from as little as a verbal warning to an account suspension or an indefinite ban against the user in question.

The staff reserves to the right to judge any given situation to be hate propaganda or acceptable speech based on the individual circumstances of each situation. This policy against hate propaganda is not intended to be used as a tool to disrupt debate, opinion or other valid discussion.
