On one particular episode of Seinfeld, Kramer joins a karate dojo. We learn that he is rising to the top and winning fights against all the other fighters in the dojo. He seems childishly proud of himself. It isn't until somewhat later in the episode when we are brought inside the karate studio and we see that all the other students there are all children. Finally, at the end of the episode, the children corner Kramer in the street to take their revenge.
You have to size up your competition. It does no good to prove points against obviously weak positions. If you are around dumb people you will play down to their level. If everyone you are in dialogue with is that inferior, then choose a different conversation.
