Oh wait, no, he was jailed for campaigning against the repressive state control Saudi Arabia has over women, according to local media.
The man was given a one year sentence by the Saudi sharia courts for publicly suggesting the current legal system of "guardianship" should end. For the Saudi Arabia theocracy, that's akin to blasphemy. Lucky for him they didn't behead him in the public square.
He was arrest while putting up posters countering the guardianship system. The court also learned that the man was responsible for a widely-reported petition against the regime.
The Saudi regime orders that every person with a uterus must have a male legal guardian, and must have permission to travel, marry and take certain jobs. They are also forbidden to drive, although if they can find someone to drive them, they can vote for someone who will be subordinate to the king.
Feminists throughout North America have voiced their extreme outrage, oh wait, no they didn't.
The man was condemned to jail and fined around $8,000 for the offense of "inciting to end guardianship of women."
The guardianship regime makes women subject to the whims of whoever is in charge of them--even if that happens to be a younger brother or even their son.
