i hear you baltar447 - but let me add something to the mix - it may be an exceptionally emotionally vulnerable person that has left the JW's (and their partner)
Would that influence how we ex-cult members treat someone trying to rebuild their lives outside the group?
Well, it might depend on the situation. But ask yourself, what if the mate that was innocent didn't do anything really bad and was a pretty decent person? Then you're offering support to the one who broke up a family. I'd have a problem with that regardless of a person's religion.
I'd find out more about it if it was me.
