I would have any and all men who have raped women and/or children castrated.
I would make birth control a law and using unprotected sex would be illegal.
Only men and women who are intelligent, don't drink smoke or do drugs, have healthy genes and will be loving and devoted parents will be allowed to breed, which is the only thing sex is good for anyway.
They would require a license and have to pass a series of tests if they truly want to have children. If they failed they would be forced to wear a device that would make unprotected sex extremely unpleasant and painful.
I would have people who have physically abused other people beaten in prison so that they will feel, perhaps to a smaller degree, the pain, suffering and terror they inflicted on their victims.
I would destroy alcohol and cigarettes and anyone caught swearing would have to pay a fine.
I would have so-called Hollywood "celebrities" put on a rocketship on a collision course to the sun.
I would get rid of all the horrible TV commercials and stupid soap operas and awful reality shows.
And I would have my own private animation studio and make excellent cartoon shows and ban all the stupid cartoons that are on TV now.
As dictator, I would have anyone who is as permanently-pissed as this fed low dosage happy-pills until they finally calm down.
