Besides their perverted theology, I have nothing against JW’s. They are polite enough in their up-front contacts at people’s front doors. Sometimes too up front. But “extremist” and inciting hatred? Hardly.
Most people don’t know that Jehovah’s Witnesses were among the groups persecuted and sent to death camps by the Nazis. Their theology is something I’ve lots of problems with, but they aren’t even really a minor nuisance for all their incessant door-knocking.
Yes, they are polite when I tell them I am not interested and send them on their way. I guess Russians don't like uninvited people knocking on their doors. Must give them NKVD/KGB flashbacks.
They may be nice to outsiders but they are definitely not nice to family members.
