Yes, like this specific seat I paid for. Or my time or energy even. I do not have to give that up for a stranger's kids. "Putting up with" the fact that kids exist is not the same as being expected to bend over backwards to parent a stranger's child.
People like you are why "/c/childfree bullshit" exists. You think that "it takes a village" means that if someone mixes their DNA with someone else's, suddenly that is the "Village's" problem and not the parents.
