All "dissent" needs to do is bring evidence -- scientific evidence.

Well, kinda. Science is a lot more accepting of arguments that say "current thinking is incomplete" than of those that say "current thinking is flat wrong."

OK, I can agree with that.

But we must remember that "extraordinary claims require extraordinary proofs" (although I would change "proofs" to "evidences").
