Sometimes a system is so bad that the only reform is a revolution. Incrementalism is simply an unrealistic option in many cases, including voting reform (and climate change)
I’m definitely not talking about a revolution in a sense of violent overthrow of the government. I’m merely talking about revolutionary changes to the voting system. More specifically how the votes are counted towards each representative. I don’t have a source for this, but I think most Americans would actually be quite happy with the idea of switching out the election system for something objectively better.
Even, a political grass roots revolution would be unsuccessful as many people are resistant to change and would not back it.
Incrementalism is the best approach as it slowly changes people and doesn't get their defenses up from the get go.
