Are you serious?
So you think that because YOU were born in a dysfunctional family and had no religion instilled in you, it necessarily means ALL children are in roughly the same boat and aren't influenced by their parents or the environment in which they were raised?
Not necessarily. You're still influence by environment and society, and the possibility of personal delusion which can rob you of real objectivity. But I'll just take you at your word for now.
In other words, when people are taught things that you don't agree with, it's bad.
I've already exposed that the very video Deeje used in the OP is misrepresentative. Do you believe it is appropriate to lie in order to protect a belief? Is that something JWs are taught is right to do?
If it's all subjective, then you have no basis to assume anything about blood transfusions. Like it or not, it is not a matter of opinion that blood transfusions save lives. It is also not a matter of opinion that children have DIED because their JW parents refused for them to receive transfusions.
But, hey, it's all just subjective, right?
