I know and sympathize with you greatly.

Not to be gross, the first time I realized it I about puked in the middle of a managers meeting. Seriously depressed and almost called in the next day.

Didn't want to be around them.

Good news you get over it, and for me, I was filled with disgust, yet sympathy for them. Over time I got a few of them to be more open minded. A few others were hopelessly lost and i/we at least knew who not to talk about it in front of them.
