Drunk Clown is an Orgah too. Instead of trying to figure out his motives, why not just addressing the points he makes?

If a valid point is raised, then that has to be addressed, regardless of who made the point or what the motives behind the making of said point are. The point is relevant, the rest isn't and just causes you to lose focus on what is actually being said by the member in question.

Let's say Drunk Clown is on a mission to overthrow the .Org dictatorship and somewhere in his posts, he points out that a staff member said 1+1=3, then there's no shame in admitting that indeed that staff member made a mistake and that 1+1 is of course 2.

Why you simply dismiss everything he says, because of his suspected "motives" or the way he handles this (not all of us have experience in changing policy in large organisations following the Lemur 10 steps program (tm) ), goes beyond me.
