Why pretend to know my motives or intents with this comment? You have no way of knowing either. I'll fill you in; only under the rule of an intrusive and over powerful government could every man's sperm be deposited for later withdrawal. How else to know that the man had complied, which makes as little sense as making every woman bank her eggs and undergo similar surgical sterilization. Compelling one sex to do this would necessitate compelling both, equal protection.
