If you can’t reach your ideal democracy without executing dissidents, that’s not democracy.
‘Dissidents’ like they’re some powerless minority being oppressed and that their dissent isn’t over the value of human life. This is why we say that liberals are the same as fascists. “Sorry freemen, if we crack down on the whites killing you and passing black codes, it’s just not a democracy!”
Ah yes, peak anti-fascism: declaring your political opponents to be monolithically evil to justify their execution. Half of all American voters are subhuman scum that must be cleansed to bring about democracy.
You can, if you stop abstaining or voting third party out of protest. You can’t blame the electoral system for being ineffective if you don’t use it right.
