Linking morals to extroverted types clearly sounds like bullshit to me.
As a person with 1D Fi and 2D Fe, I have feelings, but I have no idea what to think about them. I don't trust them and I try very hard not to let my feelings affect my actions.
And my morals are pretty situational. However, I'm aware of this and view it as a potential weakness and am therefore looking for input in this area, which I will be happy to consider in the light of rational analysis.
