The only commonality I see is that Fascism and libertarianism both reject egalitarianism. That’s not a lot to go on, really. I guess you could say they agree that the means of production should be privately owned, but even that is pretty sketchy, with Fascism holding that the state can and should dictate what gets produced. Of course there is the “everyone I disagree with is the same type of poopyhead” theory of politics, which seems to be in play with this NR piece.
Your last sentence seems to be the default mode of discourse at NR, and this has been true for several years.
We should be careful; Jonah Goldberg might read our comments in this thread and mock us with a “Courtship of Eddie’s Father” allusion.
I don't think he's saying that the ideologies are similar, but that there's a kind of person who says "I am right and the rest of the world is wrong."
When they come across other ideas that the rest of the world disagrees with, they are attracted to those ideas and in time they can end up in some very strange places intellectually.
There's an attraction to extreme or marginal ideas, also a hostility towards the average sheeple who don't question or dissent or question established orthodoxies.
There are plenty of examples of people like that out there, but one problem is that there are also people out there who'd take Dougherty himself or me or even maybe you as examples of the same phenomenon. For some people, not so long ago, National Review was seen as lunatic fringe.
I still haven't figured out what any of this has to do with the Latin Mass, though.
