If we could get a bunch of like-minded people together on the offline world, we win. It doesn't matter if we are infiltrated, we can spot those who present bad ideas, it doesn't matter if cops get wind of it, we won't be doing anything they can arrest us for, and we'd be too numerous and we'll connected to lock up quietly, it doesn't matter if the media misrepresents us, we can take them to court for it, it doesn't even matter if violent thugs show up, we can resist the urge to reciprocate their violence and relocate ourselves to a backup location disclosed only to attendees who arrive to the first location. Once we meet up in the real world, and we start talking to one another, we win. Think of what we get from this, contacts who can be used to talk with, a network of support that can protect you when you are being persecuted for your opinions, and far more, the beginning of a growing base of people that can become a politically influential force as a group where each individual would be effectiveness by themselves. The biggest problem is that actually taking the risk of going to an arranged meeting point is risky if no one else shows up, or too few people turn up.
