The key word is "deliberately." How do you prove that someone deliberately spread a false teaching??
For instance, is a R&F deliberately spreading false teachings by going in field service? I would say the answer is, "No." Why? They believe it to be true, so they aren't doing it deliberately.
This nu-light on the anti-christ is just as likely to be a loop-hole for the GB, as it is a catch-all for faders/dissidents.
I wouldn't worry too much about it being used against anyone. The ONLY way I can forsee this being a problem is if you are asked THE question. You know, " Do you believe the GB is God's channel, the FDS?"
You can say, " I don't know? It seems Jeehoober can use anyone at anytime. Brother McDouchelick, what do think about the hypothetical "evil slave?", did you know that Christendom's scholars came up with that? Seem like Jeehobo is using lots of people. That scholar can't be part of the anti-christ, can he? What about us? We have taught things that were wrong about Jesus. CTR said Jesus was going to be done with the Big A in 1914? Was that deliberate?"
If the GB use this to judge others, they condemn themselves. It WILL backfire as a weapon.
