Taking your position that you still believe in the Bible in some type of conceptualization........yes it is inviting to name them the antichrist......but yes, as other posters have suggested, its not worthy of being scared about.
Like any other group in society, their importance comes mainly from themselves and the WTS itself. Yes, you could say Jw's are a relatively well-known religion, but who really gives a fuck about them, really? They are full of their own self-importance, but I don't see them as as the antichrist either, taking a biblical route. Probably just a case of, evil is, as evil does..............image
A thing that amazed me about the wits, (and I haven't even been one), is that incredible self-confidence they project of what they believe to be true. But as Mick says, if you look at de-constructing the individuals who are often drawn to a cult such as this, this may reveal more about them rather than anything of a significant biblical note.
