Opposite of accelerationism

Tarditionalism
Like traditionalism, but with retardation (literally "delaying") being more explicit.

so fundamentalist Amish?

Even most fundie amish are not immune to accelerationism:
In 1966, around one hundred families split with the Old Order Amish in Lancaster County, Pennsylvania, over differences related to the use of modern machinery. The collective Lancaster Amish ministry forbid the use of said machinery, but in many districts, the Amish had adapted to the technology. Because of this, the ministry had a difficult time enforcing this ruling. In 1964, the bishops banned four districts from communion for not implementing the larger group’s standards on technology. By February 6, 1966, thirty Amish families, under threat of excommunication, met at the home of Christian F. Flick.[3] There, they organized a separate service where they received communion from a liberal Amish church in Newton, Ontario. In April 1966, sixty-five families had come to associate with Flick’s group. There were three defector districts in Lancaster County by fall of 1967. About one hundred families were split into three districts, one at Honey Brook and two at Gap.[4]

Even Evola admitted fight with modernity was lost. Its fascinating to see all ideological strains and movements as strands of overarching accelerationism: conflict between one and another creates progress and elevates the status of technology from a tool to a mode of operation which cannot be abandoned.
If civilization collapses it will not sustain even 0.1% of current population, since without a working technological chain the modern ways of living: agriculture, medicine and transportation start breaking down.
State structures depend on modern technology: in effect state is an expression of technological authority over the population with the tools of mass communications, public policy and surveillance. Modern states are far more sophisticated and pervasive in their coercion of an individual, with less of a possibility of rejection of the control and social enforcement of norms and ethics used as another mechanism by which state establishes its authority to interfere with individual.
The progression of states into transhumanism will be something like a mixture of '1984' and AI deciding everything in an """optimal""" way like a totalitarian dictator with penchant for micro-management and the resources to monitor everything. This is the logical outcome of accelerationism. Its hard to see this a utopia: but for some the AI being a source of neutral enforcment of the law would seem like a "fair philosopher-king" who can't go wrong.

A major black-pill is accelerationism is inevitable on global scale, because the most advanced nations will subjugate the traditional ones in time: the technological gap between traditionalists and transhumanists will become as much as gap between jungle tribes and modern man. All the inventions that change society to improve it can't be denied their usefulness and utility: the rational choice of a man will always seek towards greater progress and convenience.

I am riding the tiger, and so should you!

retardation is already explicit in traditionalism
