I think there would be Christmas Rules.
And I do not mean "rules" as in the current venacular.
There would be strict guidelines on which xmas songs you could sing or listen to. The only permissible songs would be the religious ones.
If you were in a store shopping and a santa song came on, you would be mind controlled programmed to immediately run from the store so you would not be contaminated by hearing it. I would imagine that would cause store security to work overtime chasing JWs as possible shoplifters trying to make a quick getaway.
