No matter how much we hated the JW organization, we could not support Nazi's persecution toward it.
As for this time's Russian case, I think we can't support its ban.
There is, of course, a big difference between the Nazi imprisonment and killing of Jehovah's Witnesses and the Russian ban on the religion for extremist reasons.
I go back and forth with myself as to whether I support the ban or not, but there is one single JW practice that makes me lean toward supporting it - no blood transfusions, which results in loss of human life.
If the ban goes through presumably Hospital Liaison Committees (HLCs) will not be allowed to exist and therefore cannot interfere in medical cases, which will result in the saving of life.
The breaking up of families as a result of DF'ing and shunning is big with me too, but this may continue, business as usual, since JWs will continue to exist as an underground religion in Russia. However the practice may be curtailed a little bit.
As to the human rights issue of banning any religion, it's true that Russia isn't exactly a world leader in supporting human rights, but neither are JWs who insist on freedom of religion for themselves but refuse to allow the same freedom to those who choose to leave the JW religion.
If JWs receive the same treatment from the Russian government that they have dished out to their followers for many decades, then as far as I'm concerned it's just a matter of fighting fire with fire, and I will feel that they have met their match in the Russian government.
In the end, if the ban goes through, I can support it mainly because it will interfere with Watchtower's no-blood policy, at least a little, and result in the saving of life over time.
