The "You Umpire, I'll coach" line - especially from 30 feet was not good.

I, too, think you could have handled it a little better by requesting time and instructing (face-to-face, and nicely) the umpire why he was wrong, by rule. Snide remarks like that only add fuel to a smoldering fire. You put him on the defensive, and that's why he came back at you with the threat of ejection.
