You know what beats a cry of BS, even from the masses? Evidence. If you were to prove them wrong, their claims would mean nothing. They could say whatever they wanted, but the evidence would be much louder than all of their voices combined.
As far as being neutral goes, you say they don't have proof one way or the other. That's not strictly true. As much as you have your own personal experiences to lead you to a conclusion, they have theirs, some of which relies on scientific methods, some of it experiences of their own attempts to do something paranormal.
It doesn't matter how many people have gone before ..... be polite or don't post! That applies through this entire site, doesn't it?
How do know that 'most, if not all' have been fraudulent when it isn't something that can be proven online?
Attempting to experience something paranormal and failing does not disprove the existence of the paranormal!
