If you're going to pretend yelling that people thinking the world will end by 2030 is reasonable, the burden of proof is on you to prove that credible organizations are actually saying that. Otherwise, you're just putting up a strawman of "lots of crazy people saying the world will end by 2030".
I agree, but given that nobody with any real-world credibility is saying that, the person making the claim that the "world enders" are evidence that scientists are crazy has to prove that they exist.
