Election rigging in US, Platforming/endorsing AfD, that nazi dab move, very racist views, tariffs sure to hurt US competition. Capricious layoffs, Recommending Derek Chauvin pardon in order to instigate a race war/police beatdowns.
All of the above are worthy of protests and opposition. It is overt corruption. Much worse than hypocricy of democracy he helped dictate. If the above wasn't enough to protest, the right to express opposing facts and interpreted democratic vision vs elevating that right as equivalent to support for terrorism is yet another, probably the worst, of all protestable evils he is responsible for.
Unlike propaganda vs US empire adversaries or "consensus master creed" that are simply repeated lies without ever factual examination, Musk and Trump are heavily media platformed and incriminate themselves in evil repeatedly.
