Who said your ancestors actually practiced Christianity? It’s only hearsay, he didn’t talk with his ancestors, they might have been atheist and just kept up appearances for all others. If he just believes whatever he’s told, he’s just a sheep following the wolf. Good on you for thinking for yourself. It’s the start of a beautiful fulfilling life.

I have nothing against practicing your own religion, you do you, but it should never be forced onto others. That’s brainwashing.
