Are you saying that like: A gentleman is someone who is intelligent enough to bullshit you, but chooses not to?

A gentleman is one who lies about being able to play the bagpipes.

(no, you're right, of course)

Would say, A gentleman is someone who is intelligent enough to spot Bullshit.

Being good at bullshitting makes it easier to spot bullshit.

Disagree. I think a lot of bullshitters assume everyone else is bullshitting, including when they are not.

In fact, they can't imagine a world that doesn't operate this way.

This is a fantastic definition for Gentleman/woman

My favorite version of this is: "The highest praise that one can give a man is that he is capable of doing harm but chooses not to."

Much less whimsical

Nope. An honest man of integrity already knows how to play the bagpipes and doesn't need to lie or name-drop to seem important. Bullshit is only appropriate to save the face or lives of others, or as entertainment amongst people already savvy enough to see through it.
