I understand exactly what you're saying concerning a poster becoming a "target". I've observed that on another popular forum myself.

However, if you take a look around here, you won't see that sort of ganging up on someone. It's just not tolerated. Our members are expected to adhere to a set of standards that precludes that sort of behavior. Stick around here for a while, and you'll see what I mean. Our members are much more well behaved, and open minded than those on some other forums.
