It depends. I understand what you are talking about and certain players can take advantage of me with calls like this, especially when they have a history of calling raises with 4-2 offsuit.

The problem that you have just mentioned is aggression. Many P.O. players are very aggressive, treating their A rag as if it was an AA or KK. Being very aggressive can pay off, even with a loss of chips. What most people seem to forget is that you need chips in the tournament, and one big win is great, but getting several decent sized pots can be just as rewarding with less risk.
