I mean it kinda as a joke, but there does seem to be some truth to it. The more passionate the progressive is, the less they're able to take or give a joke. They seem to be less creative (i.e. Hollywood the past 10 years only making reboots and superhero movies from comics; and don't get me started on mumble rap) If you read the QUALITY of joke memes on the "Politics" stream vs. the "PoliticsToo" meme, it seems like another good example.
