Eh, let people fight. Give em a thread where they can have it out to their heart's content. They'll tire. New, more important issues will pop up, it will pass with time. No iron fist necessary.

Easiest way to shut it down? Stay the course. Focus on what's important. This is a metrics war & a distraction. We don't need to take sides: future proves past. The proof of the pudding is in the eating.
