Sound like a trio of former altar boys to me.
Cho’a father is a Church of Christ minister who escaped from North Korea. Kal Pen was born a Hindu and I assume he still is. Pershaps some reporter can aks Cho’s father about the movie and it’s relationship to Christmas and what he taught his boy as well as how proud he is of his son and how he’s treating Christianity.
I’m sure this group would take on say Islam the same why. Sure they would. They know they are safe attacking Christianity.
