Read Marcus Aurelius, he was, well, a Roman emperor since being 17 and has by necessity found ways to keep his own arrogance and emotion in check (at least by the time of writing those notes he's known for ; earlier in life he had, for example, arranged a bath for his wife filled with blood of her lover).
In my opinion you are the one embarrassing yourself, and IRL I've never seen people arguing this way to deliver in actual things and not arguments. However, it's not that I myself really deliver too often, or cases where I do wouldn't make me feel euphoric.
And I've been wrong to be angry. It happens naturally, and I don't feel guilt, but it's wrong, so I ask your apology for this.
