I understand where you're coming from Blondie but I've felt for a long time that to DA would be the wrong thing - for me anyway. I'd feel as though I were still acknowledging their rules and procedures. After six years of inactivity and absence I don't feel the need to make that additional statement. Screw 'em.
Importantly, if I were to DA I would, without doubt, be viewed within my family as the protagonist, the one who actually caused the split, that I brought any subsequent shunning upon myself and my family. However, if I am DF'd for simply speaking my mind that is something my JW family will have to justify amongst themselves. The burden will be upon them to rationalise their behaviour towards me.
Perhaps it may help them think a little.
