This is a tough one. The Pub is open topic, but fraught with risk of degenerating into political/religious/philosophical rants. Maybe instead of banning topics/terms, insist that posters back their opinions with logical, independently verifiable facts and root causes supporting the opinion. No opinions in a vacuum. I say root causes because facts presented as evidence of a viewpoint might be verifiable but not actually caused by thing outlined in the opinion. I short, no posting opinions to the Pub without your statistician and data present to verify.
