If, at any point in a kerfuffle, a party uses his/her child(ren) or his/her childfree status as a point in their favor, they will be given one round to exonerate themselves; if they fail to return to proper argumentative form, they lose. This is waived in the event that one's child(ren) or childfree status is in any way relevant.

Corollary of Rebuttal: If their opponent rebuts this "point" with an equally fatuous, ad hominem non-reply -- "you should have given you kid up for adoption" or "you're just childfree 'cause you can't get anyone to breed with you anyway" -- both parties will be declared to have lost and will be grounded from the Internet for a week.
