Agreed. I am extremely anti-Watchtower, but I believe that the Russian ban will do much more harm than good. It is misguided and makes the Watchtower sympathetic--a small, sweet group who wouldn't hurt a fly (paraphrasing NY Times take on their pacifist/conscientious objector stance)--in the face of an unreasonable dictator that is friends with our unpopular president. From a civil liberties perspective, this is the underdog story they love to tell. The ban diverts attention from Watchtower's major crimes--major US news outlets are running the story while I probably wouldn't know about the ARC if it weren't for this site (and, to be fair, the Washington Post).
Not only that, it will strengthen JWs in their persecution complex. Borderline JWs will believe it's a sign of the promised persecution and slink back, instead of honestly evaluating the Watchtower's failed predictions and questionable teachings.
However, I don't believe governments have as much power as that, nor should they. Governments are just as capable of propaganda through education as the Nazi youth show us. But my big objection is that it won't be effective. Governments cannot ban thoughts; at best they can regulate actions. Governments can't ban shunning ordained as the will of God; never JWs also choose not to talk to people--whether it's because the person owes them $20 or for no reason at all. So they're not changing minds by banning the Watchtower.
I don't know the history of the Watchtower in Mexico, but just based on what I've read in other posts, there was a time when Mexico drove JWs underground and isn't it now one of the Watchtower's greatest achievements? This ban is only burying a problem that will rise again later on and perhaps in a much larger way.
