To answer your question, it’s because we have conditioned ourselves to believe that sex, sexual intercourse and anything to do with sexual desires (regardless if they are deviant or not) is more dangerous to the public than murder.
I suppose at this stage of the game, a person would rather be brutally tortured to death for not giving a burglar the combination to the home safe rather than be raped by the burglar and live to press charges. 🤷🏻♂️ That’s just one example of my take on why sex offenses are punished more than any other type of crime. Let’s not even get into the consenting under age teens. Oh what a danger you are if your state law is 17 but the girl who gladly consented to a sexual endeavor with you was only 16. She can’t possibly know what sex is but she is fully licensed to run you over with a motor vehicle. 🤦🏻♂️
