and that violence can only be done if it is defensive and meant to protect the innocent.

Right but every possible group that advocates for violence of course claims that their violence is defensive and meant to protect the innocent. The violent far-right neo-nazi white supremacist claims they only want to use violence to “protect their white children and their people from white genocide”. Far-left antifascist militants claim they only want to use violence to “defend their community from fascists using violence against them”. Anti-trans militants claim they only want to use violence against trans people to “protect children from getting abused and child trafficked”. And my guess is that pretty soon, we will start to see violent environmental activists who claim they only use violence to protect the environment from destruction. And the state/police/military of course claims it’s using violence “to maintain peace, order and stability”.

Nobody claims that they want to use violence just because, they always claim it’s defensive.
