Who gives a damn, ken? It's their group to run the way they like. If they want to exclude people for whatever reason, they're perfectly allowed. I think you have this delusion that every member should be entitled to membership of any group. That's not how it works. It doesn't matter. Why would you want to go there if they don't want you there anyways? I haven't an inkling of desire to join any groups I'm on a no-invite list for.
