For HuffPost’s #LoveTakesAction series, we’re telling stories of how people are standing up to hate and supporting those most threatened. What will you stand up for? Tell us with #LoveTakesAction.

This Valentine’s Day, in addition to the usual barrage of couple photos and “single life” memes, another theme emerged on social media: love as a radical, political act.

On Feb. 14, the Women’s March and other groups launched the hashtag #RevolutionaryLove, asking followers “to fight for social justice through the ethic of love” and post love letters on social media written to others, to themselves and even to their opponents. On the same day, The Huffington Post launched the hashtag #LoveTakesAction, asking people what issues they’ll stand up for.

Here are 19 tweets from people declaring that, in the face of hateful acts and discriminatory policies, love can be a powerful act of resistance.
