This is a bizarre and uncharitable misreading, and it ought to be clear that this is so from not only the contradiction you point out, but also the number of Christians in neoreaction.
First of all, ought-statements can't be grounded completely in is-statements, but they also can't be grounded completely in other ought-statements. Many disagreements that will appear to the progressive as normative in character are actually descriptive. (I wonder if this is related to progressivism's retreat into deontological rights-talk, which does make it a moral argument -- but deontology, while useful for some things, is hopelessly absurd as an actual grounding for ethics.) Is Roissy a deontologist, a utilitarian, or what? Who knows? -- his disagreements are generally descriptive ones, and, since the ethical systems that humans in similar cultures and circumstances(1) actually use generally give similar outputs to the same inputs(2) (except for unrealistic edge cases like the trolley problem), it doesn't really matter.
Second, go look at the Hestia Society's motto. The groundwork for one of the neoreactionary positions (though there isn't only one, and this particular one isn't limited to neoreaction) follows easily from a rejection of both Whig history and anarcho-primitivism: if civilization is vastly preferable to savagery, but the continued existence and advance of civilization is not guaranteed by the World-Spirit, present-morality maximizers pose a serious threat of unwittingly making tradeoffs that will be disastrous later, by weakening the foundations of civilization and contributing to collapse. Even if progressivism is a present-morality maximizer, it has not established -- and (because Whig history) is incapable of establishing -- that it is not making these tradeoffs. To even ask that question is to leave progressivism.
(Yes, this is one of those permanent states of emergency that leftists sometimes rail against -- but it's not as if they don't have their own.)
Roissy is an educated Western urbanite, and IIRC Jewish.
Similar enough for moral discourse to be possible without immediately collapsing into philosophy.
... What are you talking about? Who's Roissy? You appear to have responded to the wrong comment, written an irrelevant rant, and dragged in your voting brigade to receive +6 points.
Through LessWrong, I've discovered the no-reactionary movement. Servery says that there are some of you here.
I'm curious, what lead you to accept the basic premises of the movement? What is the story of your personal "conversion"? Was there some particular insight or information that was important in convincing you? Was it something that just "clicked" for you or that you had always felt in a vague way? Were any of you "raised in it"?
Feel free to forward my questions to others or direct me towards a better forum for asking this.
I hope that this is in no way demeaning or insulting. I'm genuinely curious and my questioning is value free. If you point me towards compelling evidence of the neo-reactionary premise, I'll update on it.
