Homosexuality was once a crime in the US. So was crossdressing. So was sodomy. At one time a woman could be jailed if it was found she cast a ballot illegally. Consuming cannibals use to be totally legal, then it wasn't and now it sorta is, but only on a State-by-state basis and only because Federal courts haven't made concrete rulings. In the UK and France, it's illegal to draw underage Simpsons characters in sexual activity, but in the US and Japan it's legal (or at least a gray area). The law changes, and prohibition shows that those changes are not always for the better.
