Depends on what they're doing. If they're in an area that is approved for their protest, then it's their right to be there and you shouldn't run them over. If they're running into the middle of the street smashing your car and threatening you, by all means, protect yourself by exiting the situation ASAP. That means driving away. If they don't get out of the way at that point, that's their fault.
