I believe you could just as well conclude that these people are not conservatives by any reasonable stretch of the word, too. But then, "liberal" doesn't quite mean what it used to as well.
People at The American Conservative [0] might be religious nuts but I don't think anyone could in good conscience accuse them of being anywhere near alt-right.
And alt-right engages in identity politics, believes in primacy of the group over individual, see "enemies" behind every tree, and want to use the State against groups they dislike. Very much like the left. And while you would not want to meet either on a dark street, both, in US at least, are, generally, clowns who would be the first ones to be sent to the camps in the Reich, or USSR, or any other shining example of what happens when either come to power.
