A 'Harry Potter' fan held up a brilliant sign in front of the Supreme Court today.

Everyone deserves to be able to marry the person they love.

Today, the Supreme Court will hear oral arguments in Obergefell v. Hodges, the case that might finally legalize gay marriage nationwide.

We likely won't know what they decide until June. But in the meantime, a Harry Potter fan stepped up to the plate with one of the best signs we've seen all day.

While many Supreme Court scholars believe the ruling will likely affect marriage equality in all 50 states, they're largely still divided as to whether it will be broad enough to impact all fictional universes as well.

Still, his point is an important one.

The ability to marry the person you love is not just, like, a cool perk. It's a fundamental right. Even if you're a powerful, benevolent wizard and the person you love happens to be one of the most dangerous dark wizards of all time.

It's been a long time coming. But with any luck, today nine justices will destroy the final horcrux on the road to full marriage equality in the United States. #LoveMustWin.
