Your totally behaviourally correct, it's because the left cannot meme.... it's a scientific understanding so attempts at displaying a mocked up attempt at emotional disgust expresses as nothing higher than just inbred minded nastiness that only other like-minded ideologues will approve.
The ability to express only ideological and programmed disgust is a human place far far short of the ability other people have to emote native disgust.

It's a special place these type left live in their heads...they can keep it actually, but I am sure at times it would be good to have the ability to feel little for any other that didn't fit an orthodoxy or for self-centred gain....wouldn't want to live there all the time though....1/3rd of all the best bits of a life couldn't exist.
