I agree with the highlighted part, but I suspect that is not what phiwum isaiming for. Rather it seems to be the word (pure) rational somehow turns particular desires, point of view, etc into an objective proposition.
I'm not sure I agree with you.
I think that what he says is roughly right, so long as we recognize that "speakers" are, of necessity, rational beings. To communicate (in a sophisticated sense beyond "Agh! Predator!") requires a bit of rationality, and this is certainly so when we consider communication of propositions.
So, what does it mean to say that a proposition is true, independent of a speaker's subjective features? It is to say, first, that it is true, but also that it is true in a way that anyone can determine, in principle, its truth. What sets "I like vanilla" apart from "This is vanilla?" The fact that anyone can determine, given sufficient access to evidence, arguments, etc., the truth value of the latter, but only the speaker has access to the conditions making the former true[1].
[1] It is conceivable that preferences can eventually be read off of brain states, so it is conceivable that even the former is objective. At present, this is not obviously so.
