Centrist apathy is a crucial part of the historical process that allows fascism to emerge, and voting for centrist politicians is essentially a way to slow down fascism temporarily while doing essentially nothing to reduce the body count in the long run.
The solution to fascism is either a social-democratic united front or a revolutionary movement capable of providing a meaningful alternative. That is the only way to "reduce the body count" effectively.
Otherwise, you get a repeated set of "centrist vs Nazi" elections during an ever intensifying poly crisis that become closer and closer and closer until the fascists get a thin enough plurality to win. Then the fascists take over, and a shitton of people die.
The "hunger chancellor" didn't save Europe from Hitler.
The Nordic Countries didn't just miraculously avoid fascism, and they didn't become social-democratic over night. It took a united front during the great depression to see that giving people actual fucking solutions would prevent a Nazi takeover.
This isn't just me being an ungrateful bastard who wants to cause accelerationism. This is a strategic understanding to ignore at your peril.
The choice is between progressivism and fascism. Centrism during fascism is like standing on a treadmill.
