The WTS as an organisation is guilty of many things and I welcome any legal pressure put on this structure and representatives. Banning the Witnesses in Russia will do nothing to weaken the organisation and criminalise individual Witnesses, many of whom are essentially harmless on a day to day basis.
This law is not being used solely against the Witnesses either. It's being used against many other organisations and is a reflection of an insidious culture of legalised oppression and suppression of some basic freedoms that seems to be increasingly endemic inside the Russian political machine.
Nobody is apologising for the WTS as far as I can tell, it's just there is a bigger picture around this ban that is far more worrying for the human rights of many, many people in Russia that have nothing to do with the Witnesses.
