I think we should keep in mind the motivations of the Russian government behind this ban.
They have banned private prayer groups - "house churches" - and have even criminalized e-mails that evangelize. They have bulldozed churches to the ground. All this is done for the official state religion of the Russian Orthodox Church who fears losing membership to protestants.
By supporting their treatment of JWs you support the rest of their actions which is basically religious persecution of anyone not accepted by the government.
