Labeling people you disagree with as terrorists. Great way to make friends, eh? It's always easy to discount the view of an opponent, but much more difficult to appreciate it.
Whether I agree with them or not does not matter. These people are provably, verifiably, objectively wrong. They are unable or unwilling to accept the wrongness of their ways. They resort to uncivilized methods of pursuing their goals. How are they not terrorists?
Saying that people are wrong without talking to them is a great way to destroy societies. There objectively are things they are wrong about and things they are right about, just like you.
We are talking about people who are endangering public health here, so while I don't personally agree with the "terrorist" stance, I still don't think it's just a case of "naming people you disagree with terrorists."
Endangering health happens on both sides. Big pharma pushes pain meds. They also push vaccines. The difference being vaccines don't normally harm people, but when they do, it's impossible to get compensation.
Pain meds can cause addiction and harm much more easily.
