Write a law that says you can’t do it. Prosecute those who try. Congratulations, you’ve banned it. “BUT BUT BUT PEOPLE ARE GOING TO DO IT ANYWAY!!!11!!!1!” Guess what else is against the law (“banned”) and people do anyway? Murder. Theft. Tons of atrocities. Should we remove those laws, then, because it’s going to happen anyway? Fuck no.
There is a distinct lack of common sense going around these days, and it’s people who push garbage like this, veganism, religion, anti-car bullshit, and tons of other things that show that we’re basically fucked.
