It seems that this has been a tactic that the JW's have used for many years.
I haven't contributed to this board in a wee while but upon my return a month or so ago, I was astounded to read about the article where the society described opposers as 'mentally diseased'.
It's a very basic strategy and one that works.
I myself experienced this with my wife during my more vocal periods of opposition to the society. For a good while I had a problem with drink. Not a violent problem or anything, just that I drank more. Often if I had been drinking I would raise points about the society which I disagreed with. I'm not talking about a slurring messy rant. Just discussing things in a very frank manner.
Despite my arguments being sound, they were put down to the ramblings of a drunk from my wifes point of view. I cannot begin to tell you how frustrating this was. Especially if any points were related to the mental welfare of our kids. It was as if my being more lucid gave my wife an opportunity to dismiss firsthand any objections that I made. Very convenient really. It saved her giving any of my points of view serious consideration.
In my opinion, the society does this all the time. Painting opposers to the religion in an extreemly negative light helps the rank and file JW completely reject any well reasoned or solid argumentation.
Calling people who oppose the religions teaching 'mentally diseased' is staggering really. It makes them sink to a new low. But it works.
Unfortunately, decent people who simply 'don't agree' with their religon are absolutely demonised.
Don't let it stop you speaking out. Even better, do it in a way that makes you irreprehensible.
