Would they do it? A great deal would.
Most of us who have left the WTS left because we realize it's a sham. And a lot of us are being shunned because of it.
Now, if we're being shunned because of doctrinal disagreements, it doesn't take that much imagination to believe we would be stoned if the WTS had its way.
Permanent silence for us whistle-blowers/an example to keep others in the cage. Win-win for the Org.
