Poker Etiquette and putting people on tilt

[jkamowitz]

I just returned from a 60 hour session at foxwoods casino playing 10-20 for the entire time. Strangely enough I only played at 3 tables but at each table I got into the same argument. People were getting mad at me because I was purposely putting people on tilt.
Ex. Hand 1.
Hero is mp3 and open raises with 88
Button, an older man who was frustrated three bets
everyone folds hero calls
flop 10 2 10
hero checks
button bets
hero calls
turn 8
hero checks button betes
hero raises button calls
river A hero bets button calls and says "jack"
I turn over my full house and win and say "i thought i was ahead on the flop"

and he went off steaming! saying that was a rude thing to say and whatnot. we got into an argument that i was not there to make friends and that he was upset that I read him correctly.

The younger players seemed to side with me while the older men just got more and more upset and often would leave my table and go to another one.

ex. 2
I cold called a typical players raise with 4h5h and after a flop of 6h7d8h i won a decent pot from an older man.
He said "what?? why'd you call with 45??"
I responded "to put you on tilt"
and he got more upset.

ex. 3
After beating a man in a pot he remarked "it's not good to take advantage of people when they're down."
and i replied "well when's a good time to take advantage of them then" and he called me an a!!hole and threatened to slug me.

I guess I am an a!!hole at the table but I can't understand why it is a bad idea to be putting people on tilt. To me there's nothing better than an entire table out to get me calling bets with marginal hands only to crack me. But time and time again people were condemning me. Any thoughts?
