What's the difference between a soldier who did speak up and not? A difference between a German who critisized Hitler and not?
The answer is not very much. They all are dead. Stance does not make a difference. The US politics looks way beyond a point where having moral ground is meaningful.
Saw this happened in Russia: like 70-80% of various celebraties were speaking up against Putin's regime, meduza.io was the most popular news source, even in siloviki's (essentially ICE/FBI/police) spaces. Regime co-opted some, others ran away to be smug about their "political position".
How? We can see time after time how direct peaceful protest fails and violent protest either is policed down or fails successfully like in Syria, Libia, Egypt.
Approaching the politics from the moral ground perspective and making martyrs is childish
