I remember a convention about 10 years ago when a brother on the platform told us that anything with aliens was unsuitable for Christians
That's interesting. I've certainly heard my fair share of whacky things coming from the platform, a local elder saying that cowboy hats were not appropriate comes to mind.
However, what sets Losch's comment apart is that he presumably speaks for the governing body. The GB has final say on what the rules are, what is and isn't appropriate for JWs, what is and isn't a disfellowshipping offense. The GB is supposed to speak with one voice. You know, Jehovah works through them as his channel and what not. Well, why would Losch go off on his own and make such a bold statement without the rest of the GBs backing? Is Losch a loose cannon the rest of the GB cannot control? Does he feel he doesn't need to get the backing of the GB before making such a statement? You usually don't see this kind of behavior where the leadership team is on the same page.
