Lawrence O’Donnell did a story yesterday on Louis Martinelli, a conservative republican activist who worked against marriage equality for years, then finally talked to gays and lesbians and saw the harm his work caused. He now supports marriage equality.

Equality on Trial adds,

National Organization For Marriage defector Louis Marinelli had a front seat for NOM’s “Summer For Marriage Tour.” He had every reason to stick with the bias that surrounded him. But because of pro-equality voices like the Courage Campaign’s NOM Tour Trackers, Louis had a change of heart. He now supports full marriage equality under the law!

His story reminds us to continue telling our stories and making LGBT people visible. That’s how we change hearts and minds.
