Right, this is the big picture nobody acknowledges. I'm not paying the price for your kid because I don't know them. I couldn't care about them even if I wanted, because their existence doesn't even intersect with my life.

Yes, as a parent, you are required to put in more effort into parenting your kid than random hypothetical people. That's obvious, and has been the case forever.

I understand the concept of community, but community is not me sacrificing my privacy for someone 1000 miles away.

If parents don't want to do X, Y, and Z to lock down their devices then that is their right. And I support their rights, so the conversation is over right then and there IMO.
