Incoherent gibberish

I read Glenn Reynolds' original piece on this, but The Talent Show reproduces the important passages, so why bother linking to the original and getting cooties from it? This section especially drew my notice:

Patriotic people could -- and did -- oppose the [Iraq] war. But so did a lot of scoundrels. And some who supported the war were not patriotic, if they did it out of opportunism or political calculation rather than honest belief. Those who are now trying to recast their prior positions through dishonest rewriting of history are not patriotic now, nor were they when they supported the war, if they did so then out of opportunism --which today's revisionist history suggests.

Now, what exactly does this mean? Honorable and dishonorable people both opposed the war. Um...er...okay. Uh, what exactly is the point of that statement? What does that statement prove, exactly? What exact meaning follows from that statement?
In any event, Reynolds had begun by claiming that opponents of the war were, by definition, unpatriotic. Before the quoted passage he said:

Reader Kathleen Boerger emails: "Could you do me a favor and define 'patriotism' please?"

I think it starts with not uttering falsehoods that damage the country in time of war, simply because your donor base wants to hear them

Of course, Reynolds at no point in his post gives an indication as to what exactly the anti-war folks lied about. The lies of the Bush Administration are legion, so gross and so numerous that it's hard to think of an appropriate metaphor.
I agree with Reynolds' following point:

...people who have spent the past year saying that Bush took us to war to enrich Halliburton somehow now think it's beyond the bounds of civilized discussion to question people's motives on the war.

But one might notice in reading lefty commentary that not very many of us make any real attempt to guess at Bush's motivations. I once gave an interviews to a reporter in my capacity as "Prospective protester waiting to board bus that will take him to site of protest" and I indeed guessed upon the whys and wherefores as to the war, but I remember making it very clear that I was just guessing as to the reasons for the war, and that as I had no real clue as to why, I was just taking a shot at it. Again, as we have so very many times before under this president, we're dealing with a straw man of an argument. At best, this rebuttal deals with a minority of anti-war critics.
