You win. I did not realize that we knew that galaxies have been flying apart for billions and billions of years, as opposed to just right now. If something has been going on for so long, I agree that the simplest explanation is that it has always been going on, and this is precisely the conclusion which I thought popular science books took for granted.
Your other arguments only hammer the nail deeper, of course. But I notice that they have a much smaller impact on my unofficial beliefs, even thought they should have a bigger impact. I mean, the fact that the expansion has been going on for at least a billion years is a weaker evidence for the Big Bang than the fact that it predicts the cosmic background radiation and the age of the universe.
I take this as an opportunity to improve the art of rationality, by suggesting that in the case where an unofficial belief contradicts an official belief, one should attempt to find what originally caused the unofficial belief to settle in. If this original internal argument can be shown to be bogus, the mind should be less reluctant to give up and align with the official belief.
Of course, I’m forced to generalize from the sole example I’ve noticed so far, so for the time being, please take this suggestion with a grain of salt.
I prefer the meme where you’ve just won by learning something new; you now know more than most people about the justifications for Big Bang cosmology, in addition to (going meta) the sort of standards for evidence in physics, and (most meta and most importantly) how your own mind works when dealing with counterintuitive claims. I won too, because I had to look up (for the first time) some claims I’d taken for granted in order to respond adequately to your critique.

Good idea! It’s especially helpful, I think, that you’re writing out your reactions and your analysis of how it feels to update on new evidence. We haven’t recorded nearly as much in-the-moment data as we ought on what it’s like to change one’s mind...
When two people argue, and they both realize who is actually right, without drama or flaring tempers, then everybody wins. Even people down the block who weren’t participating at all, a bit; they don’t know it yet, but their world has become slightly awesomer.
