Odd this would come up now. My wife and I just met some people and over wine and cheese we got to talking about our backgrounds. We told them that we have been married 42 years and that we met each other through the cult we had been raised within. Their ears perked up,"oh, really! what cult was it? " (I've been through this conversation many times before with other people). I said, well, originally they were called "Russelites", then they named themselves the International Bible Students and then in the 1930s they adopted the name "Jehovahs Witnesses". They respond, "Oh, yeah, I've heard of them!" (sometimes they know someone who is, or was, etc)
At his point I plant the poison pill. "Yes they are one of the most dangerous, controlling cults there is. Remember Jim Jones in 1978 who got over 900 followers to commit suicide by drinking cyanide laced Kool-Aid? well, the JWs have led thousands into religous suicide through their cult teachings. And so on. When I'm through I pity the next JW that comes to their door .
So all the above posts about whether JWs fit some 'definition' of a cult or not is just an exercise to me. It is a cult by any measure and when you explain it to non witnesses they see it as a cult also. Websters dictionary should define the word cult as "Jehovahs Witnesses". period.
