@Elliptica @deVoid there are more than subtle differences in your no-disgust list. Other races can be as obviously different as fictional Star Trek aliens, which also don't trigger that effect. But the curiosity/interest point has an amusing example: I've heard of a white baby that stopped crying to stare in amazement when a black guy kept flipping his hand. Light side/dark side/light side.

Serious ailments makes a lot of sense. Just look at arrest pictures of antifa.
