Self-defeating Unitarianism

Unitarians give me theological dyspepsia — they are the religious version of self-righteous liberals, offensively inoffensive and devilishly pious — so it causes me no end of amusement to read the following:

All creeds and confessions restrict belief… (src)

Yes, that's a direct quotation from a document which serves as the confession of faith for the Unitarian Christian Association. Presumably, restricting belief isn't a bad thing. Or something.

They do, though, go on to say, something I can work with:

unity is to be sought, not in uniformity of creed, but in a common standard of righteousness and obedience to the commandments which Christ Himself has laid down.

I can work with the first bit, because it gives me licence to accuse them all of believing a mass of self-contradictions, and tell them that they're all idiots for trusting their own intellects over God's word. They can't complain, because that would belie their apparent unconcern with creeds, doctrines and anything remotely belief-like. I can even go along with the conclusion, since we do all attain a unity when it comes to 'the common standard of righteousness': for there is none righteous, no, not one (Rom. 3:10, src). The only problem is that Unitarians would take issue with the Apostle Paul on that point.

I never have quite worked out how they get away with calling themselves Christians.
