This reform is simply not possible. You cannot use the same methods as the far right and expect the same result but for a different ideology. They work differently, they're based on different systems and beliefs.
And you seriously underestimate the power of revolutionary warfare. Technological advances in military warfare have made things harder, but not impossible. In 93 Russians were in the streets fighting the Russian military to overthrow Yeltsin. They had the courage, even without the military training. On Vietnam a nation and it's people successfully defended their freedom against a technologically superior army. And I don't think I need to list how many coups and revolutions have appeared over the past 100 years. You can't think it's impossible looking at history.
I am no billionaire able to fund a milita, nor am I a general. But when the time arises or rather if it arises while I live, I do have the zeal to kill and die for what I believe in.
