What exactly is a terrorist in your opinion?

What does the law consider a terrorist?

Is there a difference between your opinion and the law and do you believe the law should be revisited if there is a difference? Why?

Just curious as I had asked this question earlier when Canada was considering it and the post wasn’t approved.

Also, I have seen multiple videos of “proud boys” chasing people in the streets accusing them of being antifa or videos of these guys sometimes even getting violent with people that support BLM either because they said something or because they wore a t-shirt that showed their support. Where does that fall in the terrorism scale?
