Personal twitter accounts don't exist to be providers of commentary or contributors to conversation for you. Something isn't "unsubstantiated" just because someone hasn't accompanied an expression of their opinion (not directed towards the author or a general readership!) with arguments, proof, and textual evidence. Why should someone annotate or commentate their feelings for your benefit when they aren't even talking to you? You are the one who seems bizarrely righteous about the world not revolving around you and your desires.
