It's just the standard leftist doublethink of the past decade. Any realistic definition that labels 99% of Republicans as far right would label 95% of Democrats far right too. If their ideas were popular they would have started their own party a decade ago instead of being ground up in the DNC.
They claim "harm reduction" but that's not how just not voting works, 95% is still a super majority and anything you "win" is just tokenism at the end of the day.
