Sorry, the only thing ridiculous is that you think if you legislate morality it will stop all indecency.
Logic straight from DU.
Seriously, stop and think about this for a second. Banning murder (which all states have done) does not stop all murders from taking place. Not only that, murder laws are based on morality. Should we then legalize murder? Of course not. The same logic applies to abortion, if the unborn child is a living human being: it deserves the full protection of the law, just like you and I do.
