I love this question as it opens up many interesting considerations, but perhaps the most important one to get into your mind is, of course it is important to play correctly, but it is more important to win. One little twist on this, as suggested it appears by chisel, is that if you win, then surely you have played correctly to win that hand! It doesn't matter what your opponent thinks of your play, as in poker the winning hand is the best at the showdown, or if showdown not reached, then the person who wins the pot. If you had played badly for that hand, then you would not have won.
Dont get hung up by the poker etiquette squad...they are too busy moaning about how long it takes to play a hand or telling you what you should or should not be doing! (Keep getting into their heads!)
Enjoy your poker and keep winning!
