Then he goes on to say "normally" he wouldn't call there. WTF is that supposed to mean? I flopped nut straight earlier and this dude called me down with K high and hit runner runner flush. Grrrrrrrr!

This early in the tourney, should I be this aggressive? Considering people like this call you down it seems like it's good business to put it all in here as an almost 11-1 favorite. What about the preflop raise amount? I'm basically screaming AA or KK, but who knows what they think. I doubt they even worry about what you may have.

Don't be results-oriented. It sucks, but you played it as well as you can. If you let the idiots get to you, they win. Scroom.
