Still not terrorism.
If you label everything where people in a group get together to do violence as terrorism, the word loses all meaning. It's not as if the crime magically becomes easier to cope with by labelling it as terrorism. You aren't going to solve the problem by calling it something it is not.
Not sure I see what your argument is here. If it is violence to intimidate and frighten, and it is an ideology,and I'm arguing that it is, then that is the definition here. You didn't present any argument against what I said.
