I never felt a strong “blood” thing. I basically see life as a giant slime mold that I’m a part of and any help I bring anywhere to improve something in the species somehow helps the whole slime mold a little, so procreation was never a concern I had.
Yeah, it’s hard to know if it’s a cultural infection or something that genuinely important regardless of cultural influence.
That’s where the “is it really from me? not from me?” issue gets really really difficult to discern.
