Persecution is hunting people down and putting them in jail or killing them for BEING of a specific religion.
The JW's have never been persecuted.
There was this thing called the Holocaust. It happened back during WWII under Hitler and the Nazis. Jews, homosexuals, gypsies, Bible Students/JWs and other undesirables were rounded up and put in concentration camps. Some were killed, some died due to the horrible conditions.
You can argue semantics if you want, but JWs have been persecuted off and on. Even in the US and Canada, they've suffered persecution.
I don't like the WTS and it's faux religion but I won't let my dislike of them and what they've done to me affect how I feel in general when I see oppression from a governmental source trying to stop people from worshipping/believing as they feel they need to.
The shortcomings of the WTS/JWs is secondary to the issue if and when a government is seeking to control what people believe or want to believe.
If the Russian government determines the WTS a dangerous cult and bans them, what next? Who next? I think, for it's shortcomings even, the US freedom of religion is the way to go and caveat emptor to anyone who becomes involved with any religion.
