I once had a player at MGM NL1/2 start commenting on my tight play, which was actually more because I never saw two cards that looked at all alike at the same time for a couple hours. But he just kept on and on, initially kinda friendly about it, but then trended toward unpleasant. Eventually I snagged something I could play and raised to $12 pre-flop. This yahoo immediately yells out to the table "FOLD! EVERYBODY FOLD! Don't give him action! He doesn't give us action, don't give him action! Just lay down your hands. Teach him a lesson." I steamed quietly a while about this, since it's such a clear violation of rules, but decided this guy was SOOO good for the game I wasn't gonna say a thing, and I stayed pleasant and just kept with the smalltalk and ignored the fellow. He played every hand, raised with any two cards bigger than an 8, and was a calling station. But he'd also gotten lucky and turned $200 into $1000. By the time he left 2 hours later, he'd given it all back plus another $200. And of course he couldn't resist calling my raises once I started to pick up playable hands (probably convinced he had goaded me into playing crap). I even politely said good night to him as he left--you never know, he might be back the next night.

Most folks will get tired of trying to bully someone if the victim doesn't respond. Regardless they're trying to get you to change how you play. Giving in is playing their game.

As for whether you SHOULD change how you play with a loose and stupid batch of locals, well that's more a topic for the strategy boards.
