all i try to say is that you have to draw a line between terrorism-centered actions and democracy-centered ones; protests are in democracy but terrorism is not, as such you cannot see it as a democratic action; also there are many types of protests; should we count the illegal ones that contains killing other people as legitimate protest? for example; if some one kills a mayor and says i did it to protest something, how should we see it? a protest or criminal action?
here is an example of those terrorist supporter ''protests':
Two given life sentences for Molotov cocktail attack that killed teen
The terror centered gathering cannot be seen as protest; otherwise you legalize terrorism by saying it is a part of democracy. it is at best seen ironic.
btw, all of the gatherings of those terror supporters contain molotov cocktails; and they throw them at the public buses full of people as happened in the link or other places full of people. so They do not protest anything, they just use that democratic right as cover to kill people.
