There is plenty of proof, but the way you deflect the issue is like this: So you don't have to accept it, you set up a burden of proof that you know will, more than likely, show no paranormal activity at all.
LOL - my "burden of proof" is simply any amount of evidence that holds up under scrutiny. Would you take a drug that had not been tested, but just had a bunch of unverifiable claims as to its effectiveness? Would you expect the claimants to provide proof that it worked, or would you just take their words and personal beliefs at face value? Would you then berate others for asking for proof? .... Expect in this case I'm not even asking for absolute. proof.
And of course "I don't have to accept" extraordinary claims without evidence. That's actually a healthy, logical thing to do. The unhealthy, illogical thing is to believe outlandish claims without any objective evidence. Oh, and by the way, personal testimony is not objective evidence. It's valuable evidence, and it has a place in scientific inquiry, but it's source is inherently subjective, and therefore unmeasurable and unrepeatable, because that person's state of mind cannot be accurately replicated, and no one can seperate cleanly the inputs from their environment and the mind that processes those inputs.
It's not unreasonable for me to be skeptical of paranormal activity in the absence of the kind of evidence I mentioned above; its unreasonable to expect people should take every claim at face value.
