LGBT Indians and their allies are posting Facebook photos of same-sex love all day Thursday as a way to protest the Indian Supreme Court's decision to re-criminalize gay sex.

Roughly 3,000 people have RSVP'd to Tanmay Sahay's "Gay for a day!" event, which asks Facebook users to "change your profile picture to one in which you are kissing someone from your gender in protest of the Supreme Court of India's ruling that criminalizes homosexuality."

While India's LGBT culture has become more open in recent years - particularly since a 2009 court decision that decriminalized gay sex until Wednesday's Supreme Court ruling - the nation remains socially conservative enough for activists to worry that LGBT Indians will be forced back into the closet.

It's up to debate whether social media-based campaigns like this are effective or not; some critics label them as passive activism that keeps people from more powerful forms of advocacy. But in the wake of a repressive legal change that essentially criminalizes being gay, it's certainly heartwarming to see people rally around the LGBT community.
