Being a member of a forum does not mean being a member of an organization. In New Kach we even had some members who came only to argue and even missionize, or advocate anti-Semitism (until they actually did and were banned by my suggestion). The difference is that New Kach had a memership besides having a forum.To join the forum you only needed to register an account, even a critic could do it, except if he posted offensive stuff. But to be a member of New Kach itself, you needed to apply for membership, give your full name and address and specifically state that you wanted to be a Kachnik abd support Kahanism.
