Personally I find another factor of contempt is "failing a reverse Turing Test" where there is such high repetition and little thought that it seems as if they are organic spam bots. The inauthenticity and persistence grating seems to be a common thing given the contempt for Jehovah's witnesses, Hare Krishina's, multilevel marketers and others. Tech support forced into canned scripts are another such example - in computer science terms it seems that the low entropy becomed apparent and raises subconscious red flags.

The infamous "New World Order" conspiracy theorist archetype tends to be negative and full of put downs to their target de jure as the cause of all the world's evils. Even when it is horrifying it draws more of a watching a trainwreck style reaction.

Negativity and putdowns I would classify more as a breeder of disengagement. This is reflected by the impact of negative campaign ads being more reduced total votes than drawing more votes by looking good in comparison.
