Riversflow, the reference to the replenishment of the "tree of liberty" is unhelpful. It's cliche and generates far more heat than light.
The real reason it can be dangerous to ban speech connected with "terrorism" is the quoted term is so poorly defined as to potentially be almost anything abrasive and unpopular. I haven't seen any cohesive explanation of how the occupation of the Capitol January 6 was terroristic in nature, and yet the event broadly is being criticized as such, exemplifying why high-stakes laws against ill-defined things could have a chilling effect far broader than just those things we all agree should not occur. Is the line when protesters are unlawfully in a location? Like the middle of a street? When they advocate for things that are not currently lawful, e.g., changes in law? When they are agitated, animated and frighten their neighbors?
