The comment was that single persons should not raise children “period.” By your very statement you added a caveat onto the “period,” which renders the initial statement false. Thank you for proving my point.
I don't recall saying that. Some parents with young children sadly become widowed. Some get divorced, whether or not they wanted this; some take their children and leave abusive spouses. In effect, they become single people with children.
Who, in their right mind, would believe all of them should give away their children to a married man and woman? That's ludricous.
I respectfully suggest you're playing games with the facts by using a hypothetical situation.
