I'm breaking my heart night and day thinking about the loss of the loving people who now shun me! As long as they keep showing love to concealed paedophiles in their cult - that's the important thing.
It's a perfect example of how religion skews the internal moral compass. Granted, there are radically differing conceptions of right and wrong among various cultures and even between individuals, but regardless of that, most people still have (for lack of a better word) a hierarchy of values. For example: most people will at least give lip service to the idea that lying is wrong, yet no one would condemn those Germans who hid jews from the Nazis as a bunch of liars. In most hierarchies of value, respect for life trumps the obligation to tell the truth.
Apostasy may or may not be wrong, but to treat apostates worse than child abusers is really another way of saying that it's more important to believe the right doctrines than respect the bodily integrity of children (or adults for that matter).
"Oh, but the child abuser has repented. And if the apostate would only repent too, he would be forgiven and treated just as well as the child abuser."
So there you have it: we're not being shunned for our sins, but for our lack of repentance.
