I'm trying to understand where you're coming from posting something like this. This is a forum specifically for victims of a cult...you know this better than anyone. Are we not going to talk about shunning and the psychological manipulation that the cult uses to get people to shun family members in defiance of what is typically the strongest social bond that we form?
Yes, and we need to keep some balance and sense of perspective if our criticism of the group is to be seen as fair and valid and if we are to appeal to those leaving to provide help.
ANY claim that what the WTS does is similar (in any way) to what the Nazis or Japanese of WWII did risks being seen as a claim that the two crimes are the same.
They are not the same. There is a very vague and tenuous link which is, IMO, pretty contrived and I don't think trying to make this link helps convince people it's true or elicit sympathy - I think the correct response to this is laughter and ridicule because c'mon, it IS utterly ridiculous. We could make the same claim about lots of things - "advertising uses mental manipulation techniques and OMG, Hitler did that too, therefore people selling lipstick are literally Nazis!!!"
Here's a thought experiment if you still disagree: go tell a holocaust survivor to recount their story and then say that a similar thing happened to you and explain why. If you feel you'd be embarrassed doing that (you should) then you are not looking objectively at the claim.
