Whatever. You're ignoring my argument.
Your argument is based completely on ideology and is not realistic. Your argument is based on "if only." If only people just wouldn't have sex, they wouldn't have unwanted pregnancy, disease, etc. Wow. If only people just wouldn't swim, there would never be any drownings. If only people people just wouldn't break the law, there would be no crime!
Well, people DO have sex, they always have had sex and they will continue to have sex long after we're all dead and gone. My argument uses reality, i.e. facts like "people do have sex" and treats them accordingly with reality-based solutions like *drumroll please* birth control options.
