Simon- It doesn't really come anywhere close to the barbarism that has happened in history.
Considering that the number of disfellowshipped per year is around 30,000 or abouts since the 80's thats over a million people, Id say its comparable.
I highly doubt an ex jdubs life would be completely destroyed over not being invited to family bbq.
Edit: comparable was a bad choice of wording on my part. It doesnt compare to mass killing off of entire lots of people.
Am grumpy this morning.
