Indeed, yes they are extreme to a huge degree. At the risk of sounding repetitious as many here have given their reasons for the WT Society being extreme- I'll give mine.
1. Top of the list for me - criminal child abuse policies. The hiding of and refusing to follow court orders of the United States superior courts in releasing database files of about 23,000 names of JW pedophiles to the courts - indicates they are extreme in choosing to be fined millions of $$$$$ rather than release information concerning JW members who have committed these child abuse crimes. WHAT and/or WHO are they hiding on that list that makes it so important to break the law not releasing it to courts ? And the policy of not allowing elders to report child abuse offenses to police until WT legal is notified- does NOT help child victims, it enables JW child molesters.
2. Not allowing JW's to receive life saving blood transfusions to save JW lives. Minor JW children have died because of idiotic JW parents following this idiotic WT Society policy. Who is responsible for these deaths ? Has the WT Society been held responsible or accountable by courts of law yet for thousands of JW deaths through the years of implementing this no blood policy ? Nope. It continues to happen each year.
3. Disfellowshipping and practice of shunning approved by the WT Society of not only DFed JW's but also the shunning of just inactive JW's. This polarizes familes, breaking up relationships, causing in many cases depression and suicide.
4. The not allowing of JW members to buy a political party card in Malawi , Africa in the 1960's and 1970's caused thousands of JW's to lose their lives. Yet hypocritically- the WT Society allowed Mexican JW's to sign up to serve in the military in order to get access to spreading the JW belief system into Mexico. who is responsible for the Malawi JW deaths ?
5. The preventing and disapproving of higher education in colleges for young JW's is disgusting on the WT Societies part. So JW members are left with many unused and dormant brain synapses in their minds which turn their brains into WT robotic marketing mush to be manipulated by any whim of teaching that the WT society leaders desire to implant. Another indication of a dangerous mind control cult.
So these are 5 major things off the top of my head that makes the WT Society and Jehovah's Witnesses extreme. the problem is : the WT Society does a really great marketing job or con job at manipulating the mass media on this planet trying to avoid the appearance of being extreme. WT leaders are very insidious about how they accomplish this - so that your normal Joe Blow or Mary sitting on their couch at home or just shopping in a grocery store do not realize just how dangerous or extreme the JW organization is. All the public sees are these " shiny, happy " people knocking on their door asking them " wouldn't you like to live forever in paradise with no more death and sickness " ? It disarms people to let their guard down and they don't realize what's hit them. A con game and a total unreality that JW's try to cram down their throats like a pill you want to regurgitate.
Until more WT Society crimes are exposed and spread in the mass media - especially in the United States - WT Society and JW's will get away with these extremist crimes and activities because the constitution in the United Stated OVER protects religious rights - even when it involves thousands of people being killed and damaged within those religions. Something to think about. Religion is the bane of all mankind
