In his anti reactionary FAQ Scott argues that ever leftwards movement is not a bunch of conspiracies run by Harvard and the State Department, but rather a natural response to prosperity and power. We are richer and safer, so can afford a little decadence, perhaps a lot of decadence.
This fails to explain the ever more drastic measures applied by the state to move us left, for example population replacement, and the ever more strident propaganda in school and on television.
This also predicts that no crisis shall ensue, that we will reach an equilibrium level of leftism appropriate for our level of prosperity and power, that there is a natural level of leftism, and this natural level has moved left because we are richer, have contraception, treatment for sexually transmitted diseases, dominate all our enemies, etc.
But every other leftwards movement has become ever more extreme, moved leftwards ever faster, eventually resulting in crisis, usually a bloody and disastrous crisis. The reason that leftists of anglosphere puritan origin rule the world is in large part because all the other left wing movements self destructed horribly, leaving Anglosphere leftists of puritan origin the last power standing.
Karl Marx predicted the second coming crisis of capitalism, in which capitalism would collapse, and the saints his followers take over.
I can confidently predict the collapse of leftism, but alas, not that the saints get to win. It sometimes happens that reactionaries take over after the crisis, and all is peace and order, but the more usual outcome is outside invaders take over, sometimes genocidally, or pirates and brigands take over, and slowly over centuries the brigands transition to being feudal lords.
A reactionary victory is possible. Strange things are apt to happen as history approaches a left singularity. White autogenocide is also possible, in which first all white heterosexual males are murdered, largely by each other, then all whites are murdered (Jews discovering to their great shock and surprise that they are white after all), all heterosexuals are murdered, and all males are murdered, then anyone insufficiently leftist is murdered, then the bar for being sufficiently leftist is raised, and raised again, until some of the remaining leftists wise up and murder everyone who is excessively leftist, thus ending the crisis.
If it winds up that bad, or any where near that bad, will not end in the second coming of Charles the Second.
