The whole trash talk issue in sports is a divisive one. Some people come down firmly on either side and good lucky trying to convince them otherwise.
Old folks, people who are uncomfortable with confrontation, and uptight elitist jags who think it's always "bad for the game," are usually anti-trash talk under any circumstance. Then there are those who love it under any circumstance, even if it ends up making everyone within a five-mile radius look stupid.
But, as is usually the case, most of us fall somewhere in the middle. Trash talk is natural during heated competition and it can be a fun part of the game, as long as the person running his mouth can back it up. There's nothing more irritating than the trash talkers who cannot be deterred by anything, even losing.
