I don't eat them because when I was about 8, I was eager to help my mom clean them and just became completely turned off. They weren't full of sh*t or anything, but sometimes the cooking process just makes me dislike eating a food. I also tried tripe before (I was young and didn't know what it was), but I didn't like it.
It's interesting that people only associate them with low class, southern black people though. You'd be amazed to find out what they consider a delicacy on the Food Network/in the food world *shrug*
