The American War of Independence, French Revolution and English Civil War were acts of terrorism.
Were those acts justified? Not if you're the ones who were initially holding the power.
Systematic use of terror as a policy to induce fear in the general public to push them to coerce their government's policy was not widely used.

Here's a very recent example of public authorities describing activism against data centers as a possible vector of 'anti-tech extremism': https://www.wired.com/story/us-law-enforcement-warns-of-anti...
Likewise, the proponent of a huge data center project in Utah and the Secretary of the Interior are both arguing that opposition to data centers is the result of Chinese communist propaganda: https://fortune.com/2026/06/10/kevin-oleary-trump-administra...
As far as I'm aware there have been zero acts of violence related to data center construction, or even threats of same.
I will be happy to steer you to work by philosophers and legal researchers on the construction of 'terrorism' as a political concept and the difficulty of cleanly differentiating it from 'legitimate' forms of violent political action.
You're edging on support of a terrorist state. The entire goal of groups like ICE is to instill terror. It doesn't get more terrorist than that.
Only if what those people want is something I agree with otherwise I think the state holds the monopoly on violence and we need to mobilize it against the wrong thinker.
