That's indicated by the implied negative: "Why should he/she tell you about his/her profound paradigm-changing experience? You'll only DISAGREE and DEBUNK it!' - As if these perfectly valid choices of reaction should be off the table for some reason. The questioner can also respond: "Why shouldn't others be allowed to critically examine it? What are you afraid of?"
So, nope, not interested in witness testimony if I'm expected to treat it like solid gold before even being allowed to hear and judge it for myself. I'm not impressed by whining about not hurting feelings, either. If someone really has had such a profound experience, they ought not be so wary. Otherwise, they come across as insecure. So we're only left to wonder if the believer is merely guarding a house of cards.
