Maybe I'm a little too cynical, but I don't beleive that anyone is ever deceived into beleiving what the JW's dish out. People (myself included) tend to beleive whatever they want to and whatever they can justify for themselves. Just because you used to beleive something that turned out to be false does not mean that you were deceived. You were just given false information and didn't bother to check it out 'till now (or whenever you discovered that it was false). The rhetoric hasn't changed...your viewpoint has. It is pretty obvious that JWs aren't what they claim to be and anyone who doesn't see that obviously doesn't want to see it for one reason or other. People should take responsibility for the decisions that they make as well as the reasons that they make those decisions instead of whining about it.
There is only one set of facts...If you don't go looking for the facts, then it is your own fault if you end up beleiving something that is false
