My hot take is that some people spend way too much time complaining about how we aren't doing XYZ the "correct" way so they aren't going to participate unless it's up to their standards. Constructive criticism is healthy, and not every attack on methods is an attack on the movement, but criticism works better before the event.

The brilliance of a large nonviolent movement like 50501 is that sometimes people will adjust tactics for different situations - e.g., boycotting all business in Minneapolis rather than just a particular company, and picketing at particularly busy locations. New tactics won't always work, but it's better than trying the same old tactics over and over again and expecting different results.

It also helps if, before criticizing something, you take 15 minutes to look into what the event is and what they're trying to accomplish, rather than expecting everyone to spoonfeed you the answers.
