Thanks for bringing this point out. I suspect that there is something of this nature going on in my old congregation with regard to me. They haven't formed a committee, but one elder has asked twice to meet with me. I've been openly shunned by a few of the congregation members and I'm wondering if there is some rumour going around (perhaps that I'm pagan?! LOL).
Anyway, my plan is as follows. Avoid them - if they choose to DA me then it will not be based on something I've told them. If I can't possibly avoid them (which is unlikely but could happen) then I will threaten legal action should they slander my name.
For someone still attending the odd meeting this is clearly more difficult. If I was in that position I'd try to "fade" and bite my tongue about my real feelings. I wouldn't give them the satisfaction of DA'ing me.
