I think "protester" is appropriate for people who are protesting a political process in a political building - even if some of them exceeded acceptable behavior, committed crimes, were violent etc. Using BLM as an example, is it still fair to call them protesters though they sometimes fight with police (violent behavior), graffiti or break windows (vandalism), loot (breaking and entering)?
