I'm very surprised as to why is this so upvoted, other than the fact that some of the LW crowd really loves 19th century right-wing writers.

I don't think it's a very good quote but I'd guess that the majority of readers didn't know/notice/remember he was a 19th century right-wing writer. As such few people would associate this quote with opposition to the French Revolution, or even politics -- people would first think of such things as religions.

And I'd put money on Mohammed, Joseph Smith and Apostle Paul to have been deliberate conmen. (I'm leaving out Jesus, because I'd put odds on him being just delusional)
