Wether we agree with JWs or not, it would be good for all concerned if JWs stopped shunning, for example. I would hope we would all welcome that change if it happens.
Some people wouldn't welcome any improvement because they want total destruction. (Pretty much a mirror of worst JW instincts, ironically)
I think that's pretty stupid not to wish for positive change. For example a JW religion without shunning would clearly be better than JWs with shunning. And I do think we should welcome any positive change. Isn't that simply a statement of the obvious?
