>your "tribe" won't be around long enough to have this belief "reproduce" and be passed on.

This is an atheistic understanding of the world that a Quaker obviously wouldn't share. Self-sacrifice aren't genes or memes your tribe reproduces, they're divine truths, the logos of the world so to speak that everyone will eventually be drawn into (represented by Christ as a person).

You can't destroy self-sacrifice any more than you can kill beauty or empathy or gravity. You can kill every good person, but not goodness ultimately. The entire starting point of the faith is Jesus dying on the cross, which in early Rome he was mocked for[1] according to exactly this logic "what, you worship a guy who just died on a cross, how will that religion continue to exist?"

It is not a comment on the religious/philosophical validity of the belief as I initially understood it.

Just that for a specific belief to survive, some number of members need to survive to pass it on to the next generation, which if their beliefs bar them from killing or violence requires them to rely on people who aren't.

I don't think this comparison to early/mainline Christianity is entirely fair. It was murder, not "just" killing that was prohibited by their values.

Literally every Quaker could die today and their beliefs would still survive because we can do things like write books and publish websites now. The spread of knowledge and culture isn't limited to direct person-to-person transmission, and it doesn't depend on anyone doing violence on anyone else's behalf.

How often do you see people trying to recreate the lifestyles or belief systems of extinct cultures / societies for themselves to live by in a genuine day to day manner, and not in a academic or archeological capacity?

The content of their belief system might be known and recorded in that scenario but the teaching of it as a genuine belief/truth to live by and to be passed on from generation to generation probably wouldn't be.
