Still don't see any T. What have you got against F. Extreme endomorphs are targets for insults. There is no way someone is going to get in an argument with you without using the "F" word. And I don't mean the four letter F word. I can't help but think that to protect oneself an endomorph might develop the defensive stance of a thinking or ectomorphic type. But that would be one of those maladaptations that generate tension.
