Growing racial tensions, reckless immigration and a further weakening of already-weakened social bonds could all help the Alt-Right expand its following.
Part of the Alt Right’s eventual success may come from its anti-traditionalism. The Alt-Right is mostly (but not entirely) anti-Christian and advances a Nietzschean or neo-pagan perspective. It is thereby in sync with the growing secularism of millennials.
And the Alt-Right doesn’t wear itself out trying to defend the traditional bourgeois family. It appears to be made up largely of young, unattached bloggers. Most of those Alt-Right publicists I read focus on racial conflict or the struggle between civilizations; and they push these themes far more frankly and with less careerist backtracking than the well-paid propagandists of Conservatism, Inc. They also cite telling statistics about racial and gender differences; and they pride themselves on their openness to science as well as on their sometimes vaguely defined “radical traditionalism.”
The Alt-Right belongs to a post-conservative Right.
This is another way of saying the future success of the alt-right depends on the continued splintering of the American experience occasioned by its enthusiasm for secular ideologies.
Hence the way to defeat the alt-right, if that is what the left really wants, is to reject multiculturalism and participate in unifying the country instead of working toward its demise. And that implies supporting the radical correction of America's immigration laws symbolized and actualized by Donald Trump's wall.
But, of course, that would make too much sense, as little sense as reproducing oneself the old-fashioned way, by marrying and having children.
Idealism, of whatever stripe, is poison, but our thirst for it, unfortunately, is the well nigh inescapable bastard patrimony of our Christian past.
Or that the charm and venom, which they drunk,
Their blood with secret filth infected hath,
Being diffused through the senseless trunk
That, through the great contagion, direful deadly stunk.
-- Edmund Spenser, The Faerie Queene, Canto II, iv.
