No, when someone posts something claiming it's a verifiable fact, it's their job to support it with citation. Until they do that, it remains an opinion.
Please choose to be part of the solution instead of part of the problem. Parent comment offers you a more reasonable way to think about it; the right thing for you to do is to provide verifiable evidence against bogus claims, otherwise it's just yelling at each other on the Internet, and nothing of any value happens. This isn't what HN is for, and it sucks for everyone else having to wade through such drivel.
FWIW, I agree that the GP post you first responded to is trash.

Take a moment, breathe deeply and try to relax ;)
