I agree there would be blowback from removing him but would it be any worse than the damage he inflicts by remaining there? I would almost be willing to roll the dice.
I'm a bammer, and I even think you guys need somebody else. Not that I really have a dog in the fight or anything, but even from this side of the fence you can see the obvious slant. Especially when it is random stories that really have no point to them. It's like incoherent rambling, and you keep waiting on the punchline. Only there isn't one.
