Marlo Thomas has thanked President Barack Obama for his support of gay marriage.

The 74-year-old Thomas penned an op-ed published in The Huffington Post.

“Thank you, President Obama, for being a true descendent of our Founding Fathers, and for living up to the ideals they set forth two-and-a-half centuries ago,” the That Girl actress wrote.

“When you announced your support of same sex marriage, you did more than listen to your heart. You listened to the impassioned voices of millions of our citizens – gay, straight, family members, lovers, your own circle of friends – and you made the journey to this historic decision.”

Thomas said she hoped that “by your example, others will look into their hearts and make that same journey.”

And she added that “this transforming event is about love.”

“But it is also about life and death. We read daily about children and teenagers who are dying on the battlefield of homophobia, mocked for who they are and what they feel. Taunted and bullied for what they hold in their hearts. And driven to end their own lives because of it.”

“But now the leader of our nation has sent out the message that we, the people, acknowledge their right to be who they are, love who they want to love, and live with dignity and pride.”
