> E.g. a grandparent and a parent, two or three adult siblings raising their younger siblings without parents, a couple raising their nieces/nephews/godchildren, the family in Full House etc.
These can raise children obviously, and do it well. But it’s not called a marriage. Thanks for making my point for me.
Your point was a "marriage" is a requirement for raising children well. And a "marriage" is solely for procreation. I proved that both are false by providing countercases. You didn't even attempt to engage with the second point. And in fact you seem to be agreeing with me on my first point.
I don't think you understand how a debate works. This ain't YouTube, there's no partisan audience that will clap when you say "So then you agree with me" for something completely illogical. I can't help you any further and I wish you luck.
