They are extreme, there's no escaping that fact as Dissed has pointed out. The question now is, do the Russian authorities realise just how extreme they are? Is there an informed body of people in Russia and in the ECHR that will see through the doublespeak of the appeal and uphold the Russian ban?
God, how exciting to see this happening! Whats funny about this ban now is its not a result of a Communist government state cracking down on all religion, its a result of the JW's own doing. The Russian government have given the Witnesses some room to breathe over the last few decades which has given them time to show their true colours. Sure enough, their true colours have shown up black as pitch and the Russians have seen this and labelled them extremists.
As Besty rightly said, they're reaping what they've sown.
