They cant prove that paranormal believers are wrong. They can only prove they are right in what they know at that given time, there is always more to learn. We should have faith for them to learn more, they are helping us out more than they know. It is only our perception and their judgement that what they are doing is discrediting the experiencers and believers, I can assure you...they are doing the believers a favor. When the time comes, the experiencers and believers will have their proof through science...and they did all the work for you. Maybe not in our lifetime, but in the future they will have this proof and both sides will be right. Mark my words.
