Except it is, and not because "leftists" are bad or anything. I consider myself a leftist. It is because leftism promotes a resistance and challenging to authority and a prior belief in the goodness of the downtrodden masses. None of those are wrong per se, they are even healthy, but when they are perverted and distorted they can easily led to circuses like the cultural revolution in China. Right-wing ideologies usually promote submission to authority and traditionalism. The problems that come with excesses in that front are of a different kind.

I could with as much, justification say it is particularly associated with right-wing movements because the right promotes a rigid adherence to rules and authority, which devolves under pressure into seeking out non-adherence with progressively finer and finer combs.

Maybe in some other aspects, but a cycle of eating their own under pressure is not a point on which there is a difference. The left perhaps has more contribution from “people that were on the factions side before it gained power become genuinely opposed once it started executing power” and the right perhaps more from genuine intolerance for even the slightest deviation, but they both definitely experience it.
The idea of 'right wing ideology' doesn't mean anything, it's actually just mostly pseudo-intellectual nonsense created by the academic left.
Consider that the right are supposedly in favour of free markets and small government but also supposedly in favour of strong submission to authority? These positions are incompatible.
In reality most historical movements labelled as "right wing" were left wing, yes, that means fascism and Nazi-ism too. The latter of course even had "socialist" in the title yet decades of the academic left insisting that against all common sense and obvious observations, Nazis were actually right wing, has left the world hopelessly confused about this so-called spectrum. You can't be both supportive of a dictatorship and state-controlled industry, and a believer in small government, free speech and free markets.
