From Open Source Defense:

The cognitive dissonance comes from the fact that while someone may recognize the social value of civil disobedience, they might not be willing to personally bear the risks of delivering that value. That’s uncomfortable, and potentially even shameful. And as each person in a community navigates that internal discomfort, they each find their own personal risk tolerance threshold. When people with different thresholds try to decide whose threshold is “right”, an argument happens.
