a sweet thought, but Petra's pretty happy with her situation.
While I don't assume you to be a fractious player, that interaction did play as a fractious character. I'm all for playing your character and minimizing metagaming, but there comes a time when you have to tone it down a bit or force everyone else to metagame by not beating his ass.

We had an incident (probably well before you joined) that lead to the understanding that PvP would not occur without the consent of both players, but that this shouldn't be an excuse to be insufferable.
I'm pretty sure there is no right to "freedom of speech without risk of pummling" on Enworld, and Petra would have pretty reasonable fear of your character getting summarily gutted by some higher level gladiators with less patience than Micheal with her very breif example of his behavior.
So, nothing personal, but your character will be judged by his action even if you as a player aren't.
