I agree^^^

But even way before the kids, Nicole knew that Tom was a Scientologist when she started dating him. Before they got married, I'm sure Tom let her know that he wanted his kids brought up C0$ and she agreed or I'm sure he wouldn't have married her and found a more suitable wife.

It probably is also wrapped in contracts so Nicole couldn't renig on it.

Personally, with these kids growing up in L.A with celebrity parents, they may grow up to be more sensible than most celebrity born kids.
No drugs, drinking , smoking it sounds pretty in line with what most parents instill in their kids anyway.
I get the vibe from Nicole that she would want to be "friends" with her kids and be the "cool" parent. I'm sure she'd think it funny if her kids smoked behind the shed or coloured their hair blue.

Hence the reason why Tom doesn't want anything being undermined.

He seems a great father to me. So it's team Cruise here at least as far as his fathering skills go.
