Speaking for myself, I have noticed that being constantly disgusted is associated with physical sickness instead of a psychological belief.
I used to have a metallic dental filling, one of the silver mercury amalgam ones. I had it removed and replaced by a plastic filling. (The plastic one is giving me some problems too, but they're different problems.) Anyway back when I had that metal filling, it made me sick all the time. I could taste the copper coming out of it and it made my stomach burn. After I had it removed I wasn't sick all the time anymore.
Also, when I drink tap water, it does something similar to my stomach. I have to drink bottled water. When I drink tap water my stomach burns all day long, maybe because it goes through metallic copper pipes.
But when I feel that way, physically sick all the time with a burning stomach, it makes me feel like the whole world is bad and like everyone else is to blame for my bad mood. I have to tell myself that I'm just in a bad mood, and it isn't really 'everybody else' that's doing something bad that disgusts me. The sick feeling feels exactly like emotional disgust and disapproval.
Now that I've said that, I'm going to say also that I disagree with a lot of the values of the people around me. My values are in conflict with a lot of my society's values. I don't try to fight with people or change them but I silently disagree with lots of implied values.
I'm a Three and when I was younger I was a much more obvious Three than I am now. I used to think that my IQ and my test scores and school grades were the only thing that made me worthy of existence, and I thought that I was the most special person on earth, and if anyone was better than I was at anything, then I had no reason to exist. I've mellowed out a LOT since I got older, but I still disapprove of a lot of things other people do.
It looks like I'm in one of the 'lengthy monologue' moods so I should stop writing now.
