What about this situation made you think it warrants saying that? What is your definition of a terrorist? I thought a terrorist was a person that spread terror by acts of violence. Which is not what's happening here.
Never mind the constant attacks and attempts to silence opposition, both online and off.
If you don't want to call them terrorists for weaponizing politically motivated terror, then radical extremists is another option.
Also the "paradox of intolerance" seems to apply here i.e. you can't call for inclusion without letting people have opinions you don't like.
