Here's the 411 on Detroit's Marriage Rally at City Hall on Saturday from the Facebook event page:

Detroit-Support Gay Marriage. Come out and be heard against the defeat of proposal 8.

This is not a California issue. This is an issue of equality across America. Stand up and make your voice heard. Join us in Detroit on November 15 to unite our voices against H8 and other recent legislation that seeks to make second-class citizens of LGBTQ Americans!

This is a nationwide event. Every major city in America (and some around the world) will be protesting on 11/15 @ 1:30 pm EST.

Please join a protest near you. A full list of protests by city can be found here:
