Isaiah Washington's PSA -- Now on Video!

Grey’s Anatomy star Isaiah Washington, aka Dr. Preston Burke, recorded a PSA for the Gay, Lesbian & Straight Education Network, which will premiere Thursday night on ABC.

This is in response to calling co-star T.R. Knight co-star a “faggot” last year and then repeating the word at the Golden Globes. “No, I did not call T.R. a faggot,” he told Access Hollywood at the Globes press room back in January. “Never happened, never happened.”

In the PSA, Isaiah says, “Words have power, the power to express love, happiness and joy. They also have the power to heal. When you use words to demean a person because of their sexual orientation, race or gender, you send a message of hate – a very powerful message. But we all have the power to demand better of one another, and ourselves. We have the power to heal and change the world with the words we use.”
