As can be expected in this day and age, the demonstrations are not only taking place in Washington. Facebook has become a hotbed for marriage equality supporters, as profile pictures change to a red version of the Human Rights Campaign's logo.
The HRC, the largest lobby group for LGBT rights, shared a pink and red version of its navy blue and gold equality symbol logo on Facebook Monday.
"Follow @HRC on Twitter and at www.hrc.org/blog for live-updates from the first day of at the Supreme Court hearings. Make sure you wear red to show your support for marriage equality. And make your Facebook profile red too!," the post says.
The logo has been hard to miss on Facebook news feeds, especially after Star Trek star, George Takei's profile picture change garnered nearly 40,000 likes from his enormous fan base Tuesday morning.
"For those friends wondering, this special 'red' equality symbol signifies that marriage equality really is all about love. Thanks to the Human Rights Campaign for this effort. Please consider changing your profile today in support—esp if you are a straight ally," Takei wrote.
The HRC has also started an online petition, which it hopes will gain significant traction.
