All "true" christians self-identify as persecuted even if they have to become so obnoxious it would be impossible not to fall into the trap of making it tough for them.
When Judge Rutherford whipped up the combative spirit among the Russellite leftovers he made enemies right and left among the nations of the world, the churches and in schools and courthouses. JW's really get off on persecution!
There is so little in this religion that is real and verifiable it is incumbent upon each JW to do everything possible to provoke persecution.
That, at least, is tangible!
The secular world can never rid itself of the mythos of religious zealots. It only drives them deeper into their fantasy.
But, you can't blame any government for thinking it might avoid controversy by marginalizing a religion such as Jehovah's Witnesses.
What would actually work better than banning would be creating a large public forum for exposing the craziness in public debates designed to enumerate the failed prophecies and deaths engendered by radical beliefs.
You defeat bad ideas with better ideas; not by banning.
