Freedom of worship ends where child sacrifice begins. Even in the "freedom of religion" US, parents can't slaughter their children in sacrifice to "god". Yet, that is what Watchtower Corp. does when insisting refusal of blood, clearly in the case of children, but similarly with the threat of disfellowshipping for adults. It becomes human sacrifice.
Maybe, but banning a religion outright not only violates the US Constitution (I know we're talking about Russia) and the Bill or Rights, but it's akin to burning down the forest to keep warm. It's a slippery, and illegal, position that can come back to haunt and would never pass constitutional muster regardless of what anyone thinks or wants. As such it is pointless to advocate it here. Besides, there might be other means of dealing with the problem while at the same time preserving our cherished First Amendment rights.
For instance, there are laws on the books right now that could MAYBE curtail their activities. Tort actions (wrongful death and intentional infliction of emotional distress), Defamation (slander and libel), a civil claim for damages resulting from extortion, false imprisonment, perhaps, federal and state stalking laws, .... I'm sure there are more, invasion of privacy. Look into their finances - maybe you'll find something. It probably hasn't been tried yet on a large scale, but it will in the future. Class actions are a powerful tool.
With respect to sacrificing children on behalf of the blood prohibition, I don't know what the law is. But banning the religion outright is unamerican and highly unlikely. And when the day comes (which might be closer than we think) that the government can dictate what they say and write, then we all need to run for cover. It is happening in Canada already, labeling anti-gay sermons as hate speech. Let's hope we never sink to their level although the WW I era might resurrect its ugly head. And, as far as "sacrificing those children to a god" I believe the courts uphold that right or am I wrong on this? I don't know what the law is and it might be a state by state issue, but how else can parents get away with witholding blood transfusions unless it is legal here in the US?
By the way, does anyone know if they "sell" their literature in other countries or if they only take "contributions" like in the US?
