The problem is and why I must disagree is that I do not play games with people who try to cause trouble. I do play games with book fans (some dragon lance some FR some both) I do play with people who try to role play interesting and fun characters.

I have seen a one off weird character cause trouble before... but every single kender has caused trouble.

one of my best friends since high school ran a game and a young woman who had NEVER been a problem asked to play a kender... it was a problem. She has since played an assassin, a paliden and at least a dozen other characters. What made that one different... maybe the flavor text and background given to her by the books...

I even watched as a group who I ran had someone trying to bring in a kender. The problem in this case was the restriction we put on him of not stealing from the party made it no fun for him... yet in campaigns before and sense he has never been a problem.
