Traditionalist

(In an informal sense)

a member of an online group of millennials and gen-z’s that aim to revive the initial cultural ideas, philosophical foundations, and ancestral beliefs of Western civilization.

I.e. the belief in God/gods, gender roles, and the idea that ‘life calls for responsibility’.
They generally oppose secular modern beliefs.

“She says she’d like to be a stay at home mom one day and have her husband provide for the family.”

“That’s because she is a traditionalist.”
