"Soulism" is a dangerous, existential threat to humanity that must be stopped

I'm glad you enjoyed it! I will say to the people in your Discord: it's idealist because it's a parody of an idealist ideology, and, it's not "a bunch of Enlightenment thought guys" it's pretty much just me having fun. Also I'm definitely not "the mainstream," though I suppose if you're in a sufficiently distant stream, anything else is "mainstream." I do not actually represent any kind of larger organization, Technocratic or otherwise, I'm just a random person who stumbled across your ideology.

I'm sure y'all get plenty of people telling you all the time that what you're saying is impossible, and if appeals to reason and evidence could convince you, you wouldn't believe it in the first place. Imo it can sometimes be more effective to play along with people's nonsense than to flatly deny it. Like many niche communities, you have a set of counterarguments prepared for all the common responses you get, and since most people write you off without serious engagement, it works. My hope was to take you off-script (and also to have a laugh) by walking right past all your outlandish claims about reality and criticizing your position from an angle you hadn't seen before.

A soulist utopia will not look like the pre-consensus-reality that Objection describes. It will be a world where everyone is a mage. Where everyone has freedom over their own perceptual world.

Here you fall into Utopian thinking. This is the same sort of reasoning that I often saw back when I wasted my time arguing with "anarcho-capitalists," "This mechanism could be used harmfully," "Oh, well we don't support it being used harmfully, we only support creating it so that it can be used for positive results." No no no, that's not how this works. There's no form of power than cannot be utilized for harmful purposes. Ancaps love to talk about boycotts and loss of reputation keeping companies from doing evil things - putting aside whether that could be enough (it wouldn't) - there were times in history where a company doing business with a black man could tank it's reputation in a community and cause racists to boycott it. If boycotts can be used to enforce the values of a community, then they can be used to enforce the values of a community even when those values are bad.

It's the same sort of thing with this. Putting aside the question of whether it's possible to change reality to make people into mages (it's not), you still have to accept the possibility that, given the power to reshape reality, there are going to be bad actors using that power to harm others. There is no actual reason why I could not turn myself into a dragon and start burning down cities, except that it conflicts with your perfect idealized vision of how things would play out.

Anyway, in the grand scheme of things your community isn't a big deal to me. It's a unique set of brainworms to unravel so it's kinda fun to engage with, but it's ultimately harmless nonsense, so long as y'all don't start stepping in front of trains to prove they're not real or something. I do find it annoying when y'all try to bring this into politics and try to divert energy from projects grounded in materialism and reality, but you know, I enjoy playing Mage: the Ascension and if you wanna go super hard into method acting or whatever with it then it's no skin off my back.

Edit: looking over it again:

Where everyone has freedom over their own perceptual world.

This is literally just solipsism.

There are actually two major competing schools of soulist thought. There's the cool anarchist soulists as represented by http://soulism.net and The Outside, and there's the authoritarian pedophile fake soulists lead by Azsula, who have their own website that I won't link because I don't want to contribute to its page ranking on Google.
