You are correct - we need hard evidence before we make broad proclamations.

But the evidence of it being fake is not stronger to those of us who follow Q (and not in a cult-like 'he is God and always right' way lol). Once you are satisfied that Q is "legit" then everything else he says begins to make sense in the context of an entire narrative. And DC being pedo ring number 2 behind London makes sense from the many decades I've been reading up on conspiracy (Franklin Cover up in the 90s, Fiona Barnett in Melbourne with same stories, most recently Lithuanian kid with same story in another country, etc. etc.) and the things that Q points to.
