Agree with OrphanCrow the blood hypocrisy is truly shocking.
Talking the mountains of blood it requires to produce blood products like factor 8 but not contributing a drop of blood themselves.
There are other analogous hypocrisies: such as refusing to be involved in politics but insisting on their rights and privileges in liberal democracies.
They complain about mankind "ruining the earth" but engage in no activism to save the planet, instead waiting on Jehovah, while printing their tons of literature, with inevitable environmental consequences.
Until very recently they had the cheek to point the finger at the Catholic Church over abuse scandals.
They encourage outsiders to examine their religions with an open mind, but forbid their own members from doing the same.
It's not difficult to think of hypocrisy with JWs. It's hard to know when to stop!
