Don’t shy away from the fact that you’re a Communist, but be sure not to force feed your views either. Or else, this would make those around you to think you’re there only to fight for yourself, rather than for them;
Try drawing parallels with that of their demands and the class struggle;
Be sure to dress normally while doing these events. Don’t go in dressing like you just came out of 1930’s Russia, or 1950’s China. This would then only alienate yourself away from that of the masses;
Don’t go carrying around pictures of Che or Chairman Mao, etc. While we may look up to and uphold these people as great revolutionaries, this too would only alienate ourselves from everyone else. We should carry the banners of the oppressed, combining both the demands being sought out with a clear class understanding;
Gradually show them who the real culprit is to these economic crimes as you struggle with them; and
Try being as polite as possible, even if one tries provoking you.
Without the masses, there is no revolution. And so one must be there for the masses, not the other way around.
