Jet again forced to believe

..I thought that maybe I should never tell him about my atheism..

Depends what you mean by "atheism", as there are different types.
For example some atheists like Jesus as a man, but they don't go to church and haven't been baptised or any of that razzmattaz.
That's fine, so if your dad asks you if you're an atheist you can reply "Well, I like Jesus", and I'm sure he'd be happy with that reply.
After all, there's nothing to dislike about Jesus is there? He was a rebel and revolutionary and blew the snooty priests out of the water, so he's a great role model for us all..-
Below- he said to the priests-
"You're full of shit!" (Matt 23:27)
