Can happen, has happened. More than once. My opinion remains the same.

If you are dumb enough to kill yourself because a silly little toy told you to, then odds are it's not the only thing that would have ended your life eventually. And you can't say that it's the mere presence of a vice either, in my opinion. If you drink yourself to death because alcohol exists, you were going to fall down some hole somewhere at some point in your life.

For me, it's pragmatic. My children will have a better life, if the kind of people who got lawn darts banned weren't in it.
