No, it's not okay. Bullying is not okay. It's a belief and I believed until I was 13 because my parents did such a good job and plus, it was fun. Now every Christmas is like " Oh, you got me a gift.. cool.." because Santa is no longer in it.. Let a person believe as much as they want and just play along with it.
Sounds American and Christian.
So long as it's OK for my child to shiv your child for being a bully.
