Traditious, not religious?

Thought his was pretty interesting:

I was chatting about this with Dan Savage once (namedrop alert!!), and he said something along the lines of “non-religious Catholics need to learn how to be Jews,” meaning it’s possible to hold on to the various rituals and traditions without actually being a believer, as many non-religious Jews do.

Has anyone seen/heard Dan Savage talk more about this?
