The program of birth controllers is a direct and powerful appeal to sexual indulgence

“Birth control destroys mutual marital affection and respect…Birth control destroys mutual respect.  For it is what Bernard Shaw calls ‘Reciprocal Masturbation.’  Birth controllers who surfeit themselves with sexual delight, then defeat the reproductive purpose and consequence of that delight, are more unnatural and disgusting than the ancient aristocracy of Rome who used to feast to repletion, then take an emetic (pardon the reference), vomit and return to another feast.”
