This goes to all the peeps who support parliamentary voting as a valid political action.
If your society has been steadily progressing towards fascism for decades regardless of your voting (like the USA has been), is there any point, any action which will convince you that voting ultimately doesn't work?
Is so, what is it? What would your government have to do for you to acknowledge that voting doesn't matter? For many people, it was of course, supporting genocide (which is why so many states desperately try to deny a genocide is ongoing). But if genocide isn't, what is yours?
Eventually a society which has been slowly progressing towards fascism regardless of voting, will become fascist. And we all know what comes after that. There's always one thing where I think even the most hardcore parliamentarian will agree that voting ultimately didn't work: When they're personally being force-marched to the mass grave-sites.
Would that be your point? Or does it come earlier? If so, when?
If they do not vote but also don't do direct action, they're just apathetic, which I also totally understand since the system is faling most in the working class.
It makes a lot of difference if people see others do other things than take part in electioneering to better the world.
