That's not what that study was about, like I said.
You say that what I'm saying isn't your point when I'm quoting you.
Here, I'll even quote what you just said:
my actual point, that those who believe in the legitimacy of change via a system do not feel pressured to organize against it.
Which, to boil this down a bit, you believe organizing is good, as this leads to a communist revolution.
You believe voting causes people to organize less, because they will feel like they can change things within the system instead of organize, and then have a communist revolution.
Which means voting leads to less organizing.
Which to put into simple terms, as far as you're concerned, voting bad. Hurts the revolution effort.
This assumes that dictatorships which don't let people vote are somehow easier to have communists overthrow, and that it's better to have an authoritarian government for the sake of the revolution. Because that'll rile people up and make them more motivated to organize. It's also assuming that, taking this high minded theory into the current situation, that all the trans people and brown skinned immigrants are acceptable losses while an authoritarian dictator takes over, so people will be more motivated to organize.
This also assumes that people who vote and participate within the system become less motivated for organizing, rather than more. People can start voting, then become more active locally, especially if they start seeing some of the problems within the system first-hand. People who don't vote, who start voting, I would argue are much more likely to become informed about what's happening politically, if even by the merit of looking at the ballot they would otherwise ignore.
That study does not prove otherwise, and states that people who are against the system will butt heads with people who want to maintain the system. That's kinda it. It doesn't say anything about voting, and certainly doesn't say anything about people not feeling pressured to organize against a system.
So, again, your whole assumption that I'll shorthand as "voting bad" is baseless, accelerationist, willing to throw minorites under the bus in the short term and probably long term, and disenfranchises people from what power they have over their government.
And hey, that was all from your quote right there, too.
