I like this proposal from Dan Savage:
Here's the idea: one gay or lesbian couple—a couple currently denied their rights under DOMA—shows up at the entrance to the White House grounds. A different couple every day. They ask to speak to the president about DOMA. They're refused. They sit down. They refuse to
leave. They're arrested, carried away by the police.
Couples would be recruited from all over the country, demonstrating that gay marriage isn't just an issue in liberal California or godless New England, and the media in each couple's home city and state would be notified in advance of their arrest. The occasional famous couple—Rosie and Kelli? Ellen and Portia?—would participate to pull in celeb media. But most of the couples who come to D.C. to get arrested would be average folks. The couples would need support, legal and logistical, and we would need someone to organize media outreach and maintain a website. The website would include a photo and profile of each couple that comes to D.C. to get arrested, collect all the press, and be used to recruit couples willing to travel to D.C. and get arrested. The action would be small scale—it would be human scale—and it would go on and on and on.
