Whenever the WTS discusses religion, they usually just lump them all together, giving them pretty much equal mention. They seem, as least currently, to be careful not to single out any particular religion, especially ones dissimilar to Christianity, so as not to seem religio-politically polarized. In terms of being “afraid” to slam Muslims, I think that they are more concerned with their public image than the actual safety of individual members. (Remember Malawi?) As for the WTS itself, I have a feeling that the new Warwick compound will have plenty of security measures – just in case.
The GB is definitely offended at least as much as Muslims, but at least they don’t advocate physical violence like Muslims or aggressively sue people like Scientologists. Although, the GB sure doesn’t mind inflicting its mental torture and coercion, not to mention blackmail. The GB is hypervigilant in categorizing and judging people’s beliefs, opinions, and practices, but they don’t really need to let things get to them, at least internally, because they know that they have their ways of dealing with “offenders.”
