The question of political / conspiracy theory content

I'm more willing to discuss Flat Earth, AGW, even Contrails over libelous stuff like Pizzagate...though as others point out it's hard to see why any of this would be part of the forum.

On criticisms of science as practiced, I think that does have relevance given the materialist religion often appeals to scientific consensus and assumes objectivity on the part of materialist scientists.

I do wonder about simple criticisms of psychiatry or vaccines, this leans toward offering medical advice which seems beyond the purview of this forum? Again, it may not lead to legal liability but it seems to invite moral culpability? I would even suggest disclaimers for content related to psychedelic medicine or magical healing spells.

It's kind of my earlier point. I mean weather modification is not some pie in the sky fantasy. It's big business and it's already happening all over the globe. What contrails might contain could be up for discussion but to say that contrails are some crazy nutter conspiracy theory only belies a lack of research. 

So where do we draw the line? What can and cannot be discussed? Is it "must have some relation to psi?"
