I am pretty sure Dante was not calling you a jackass, derroehre. Far as I can see it, you two were engaging in a hypothetical discussion. It didn't look personal at all to me.
To be sure, there are any number of games and game mechanics that people could argue over. Hell, I got into an argument without even realizing it (my GM thought I was arguing, and I was just confused and trying to understand what he was saying) about regular, old maneuvers in-game. A GM could come down hard on players, players can buck against a GM's ruling, and the table can fall apart. People are fully capable of being jerks to each other for the silliest of reasons.
Nobody is perfect. We all have interpersonal issues that we have to work on. But blaming players leaving on a talent is like blaming a divorce on a scrubber sponge. It's not a game issue; it's a people issue.
