If I take what you just said literally, then of course I’m right. Whether or not an ice cube is locally ordered does not disprove that an interstellar cloud of gas is “disordered.” Or more to the point, since a net increase in entropy is
always dictated by the second law of thermodynamics, the "order," imposed by ice freezing (that is - water in going from liquid to solid
decreases in entropy) is more than compensated for by the attendant
increase in entropy in the surroundings.
However, let’s take each quoted statement independently.
So you’d disagree that there’s a continual increase in entropy for the universe as a whole? Well done, sir, you win a Nobel.
Now, I’d even make the argument that star formation is a fundamentally entropy-increasing process. If one considers matter as a series of states – wherein each “state,” is defined by four variables: (1) The number of nucleides in the atomic nucleus; (2) the number of attached electrons belonging to the atom, (3) the phase of the matter in question, and (4) the relative order (in terms of space between atoms/molecules, orientation relative to one another, etc.) – then the process of star formation and fusion is, I would say, unquestionably a process which increases entropy. It increases the number of states available for matter (by fusing hydrogen into helium, etc. etc.); changes the number of attached electrons (although electrons in stars are generally not associated with one specific nuclei – damned heat); doesn’t necessarily affect the phase (in that stars are made of plasma) until after the star dies; and atoms are generally not in any particular ordered conformation or three dimensional arrangement. Contrast that with what you have in an interstellar cloud of hydrogen before the star forms (wherein only one “state,” is freely available) and the formation of a star is, again I would say, entropically favorable.
See, by way of corroboration:

So, my statement that the laws of the universe – including (for example) gravity – move the universe towards greater entropy is absolutely true. Now, was I technically incorrect in defining “entropy,” as “disorder,”? Sure. But again – I used the colloquial definition you used first. If you want to call me on such a tiny technicality, fine – I was wrong. But you were too – and you were
first.
I disagreed with your definition of entropy. And I stated that the early universe – shortly after the big bang – was in a lower entropy state than it currently is. How, exactly, is that statement wrong?

None at all... as soon as I'm actually wrong. Let me know when that happens?
