NC for this and flameproof onsie donned.
Firstly, please could the word woo be dropped as it's erm, puerile and derogatory spring to mind for starters. Pick something else that doesn't have such a confrontational connotation.
The situation here whereby some people want to discuss 'otherly' topics and others want to shout them down is pretty prevalent internet-wide
Here's how discussions involving Christians vs Atheists was sorted on one large site which is fairly strictly moderated.
"Acceptable civil discussion includes explaining your own beliefs, but respectfully accepting that others have the right to make up their own minds and arrive at their own beliefs for themselves. Discussing those differences is fine too, as long as it is not done in a patronising, insulting, demeaning, or otherwise uncivil manner. And it is unacceptable to insist that your own personal beliefs and interpretations are incontrovertible fact and that those with other beliefs and interpretations are clearly wrong/stupid/evil/etc."

Okay, so bear with..
Extrapolating that attitude towards discussion of 'otherly' topics and to avoid the need for strict moderation, here's an idea.
There is a vast difference between facts and opinions/beliefs. Clearly stating which is which can save all of the nastiness and thread-derailing usually seen in these types of discussions.
e.g. If you said 'I found an angel-feather' it instantly pushes all the buttons on the 'claimed as fact'-obsessed brigade and they can't wait to tell you birds have feathers and angels aren't real, because the way you worded your statement inferred to them that you stated a fact. And they'll argue about it forever how you shouldn't make claims, there's no evidence, ad infinitum.
However, if you'd said 'I found a feather today, I choose to believe /it's my opinion that it's an angel's/it shows an angelic influence" etc. then said brigade have nothing to argue about. You have clearly stated a belief or opinion, you have not claimed anything is a universal truth which they must challenge, you have not said it's a fact so they cannot challenge you to provide evidence.
If everyone could just try that very simple approach, then it's my opinion that discussions of 'otherly' subjects could take place as long as it was made crystal clear that what was being said was opinion, belief or as is indeed now is the case for Mindfulness, verifiable fact.
