It's a conundrum for sure. You have a totalitarian style government looking to ban a totalitarian style religion.
While the dubs will definitely play the persecution card should this happen, and get exposure in the West, it is an opportunity to point out the flaws of the WTS to JW family/friends.
When a JW carries on about being persecuted/banned in Russia, agree with them. Yes, it is a humans right violation. Every human should have the right to believe and serve the religion of their choice - without persecution or punishment. Any organization, be it governmental, or religious or private, that looks to punish, black list or shun someone who chooses to worship differently than their collective should be held accountable for their human rights violations. Emphasize the word 'shun', and leave that thought hanging.
