I second kairos, I looked at all apostates as nutcases and it had no effect on my beliefs at the time, plus just disrespectful. I allow JW's to believe what they want without trying to influence them, as I don't want them pushing their beliefs down my throat either, even thought I used to be one.
It does take away from our argument that we would like them to respect our right to believe whatever we want to believe, when we can't even respect their rights to believe what they want to believe.
