Well, of course! It's much easier to track the activities of groups that have public meetings, have public screenings of movies, etc etc. It's quite hard to track the activities of groups that have private meetings, don't publicize themselves, and maybe even require some kind of initial screening of new members. That's probably why anti-war Quaker groups always get tracked by "anti-terror" organizations, too. The Quakers actually let people in to their meetings, and invite participation!
