Unlike you I had a very brief poly experience and came to it with some reluctance. Married and mono for 15yrs ...but I know exactly what you're talking about ... most of the time it was subtle seldom has been in your face. In general I felt that there was this sense that "we" poly people are more enlightened....higher evolved....really really in touch with themselves emotionally, with excellent communication skills, and a very highly evolved intuitive abilities, etc. These intuitive gifts allow them to know how and what you 're feeling maybe even before you do....truly a great gift to have. The poor knuckle dragging mono guy just doesn't get it...he's been so indoctrinated by society and modern civilization he just can't see the light..the truth...the infinite love and beauty of it all. Poor dumb fuck...pet him on the head and check to see if his nose feels wet and cold.
I think I've read on here several times that ....poly people have higher IQ's and are higher educated or hold more advanced degrees or something along those lines. I'm not sure of what the context of those comments was at the time ....and I have no way to prove or disprove that statement ....but I think it speaks to the notion of some sort of mental superiority.
