Okay, I have to say that this whole Cofty's law thing is driving me nuts, lol. If there is a valid comparison, then there is a valid comparison, and you cannot hide behind a made-up law just to invalidate a comparison. It is valid to call something reminiscent of the nazis and their mind-set if it IS reminiscent of them... because we should remember and stop ourselves short if we are adopting that sort of mind-set. Since that is the law that cofty's law is based upon, then it should work the same.
Now if the comparison is made to state, 'you poor thing, you just can't break free of the WTS', then by all means, call someone on that one... because that can also be a way to invalidate that person's opinion. (Of course, you realize that atheists also do this to those who left the WTS, but did not leave Christ and God.) Sometimes, it is also done in all sincerity, and this is done by most everyone here, in some form or another.
Personally, I just prefer to call it what it is without the comparison to a touchy thing... because this black and white thinking; this I am right and every other view or way of doing things that disagrees with me is wrong... is common among far more than just JW's. When anyone employs this type of thinking, atheist included, then they sound no different than the fundamentalist types usually being railed against.
I do not think it is possible for two opposite sides of a view to agree with one another... that kind of goes without saying. But it is possible to be respectful of someone else's view (as long as it is not hurting others), even if you disagree with it. And if it isn't possible for you to do this, then you should reflect upon your 'black and white' thinking.
Peace,
