I feel like a lot of people are doubling down now because the Democrats on the one hand show utter incompetence and unwillingness to fight Fascism in the US and on the other hand keep up their support for Fascism and genocide by Israel.

Everyone understands in their subconcious but many deny in their conciousness that things will not get better without a struggle. So going down the "i did harm reduction, you were all wrong, lalalala" route makes them feel like they did something and helps to not come to terms that they have been strung along by the Democrats for all those years.

"we deserve non-squeaky brakes, and I won't use the squeaky ones!"

The analogy does not hold up when change can be affected by the individual.

Is the squeaking sound in your analogy the genocide of Palestinians?
