And we're not talking about an ugly technicality buried in the bylaws of, say, Mississippi -- as recently as 1983, it was still legal for a man to rape his wife in 33 of the 50 states. And this persisted until 1993, when North Carolina became the last state to get rid of laws which explicitly stated that rape wasn't rape as long as you were married to the victim.
Even now, the old laws still haven't been completely purged. In Ohio, as well as some other states, marital rape still isn't considered rape unless there's violence involved. So you can totally knock your wife out with a roofie; just not a baseball bat. And feel free to pile on all the emotional abuse and pressure you need to bully her into having sex with you, because that's all part of a healthy, legally sanctioned marriage, according to the state of Ohio.
Congratulations, Browns! You're officially not the shittiest thing about your state.
And before foreigners get too smug, the UK was only two years ahead of the US, criminalizing rape within marriage in 1991. You may recognize that as the year Bill & Ted's Bogus Journey came out. So yeah, criminalized marital rape in the United Kingdom is exactly as old as Bill & Ted's Bogus Journey.
