Your personally free to shun anyone who you decide deserves to be cut out off your life.
But the issue as I understand it ,is when you try to influence others to shun the individual and encourage them to cut off association with the individual .
So when jws make a announcement saying touchofgrey is no longer a jws ,they are basically telling everyone who hears the announcement to shun them, that's when it could be considered a hate crime.
Which is probably why they are saying it's up to the individual to decide whether they will shun the individual or not ,but as usual they are speaking out of both sides of their mouth at the same time.
