In an ad released Wednesday, Pat and Dan Lawson of Maine ask for their gay son to treated equally.

Gay marriage supporters are returning the issue to the ballot box after voters in 2009 narrowly repealed a marriage law approved by lawmakers with a “people's veto,” known as Question 1. If approved, Maine would become the first state to legalize such unions with a popular vote.

In the fourth video in a series of first person accounts from Mainers United for Marriage, we meet the Lawsons, who have two sons they say are treated differently because of the sexual orientation of each.

“We have a set of twin sons, one's gay and one is straight,” Pat says in the 30-second ad.

“When our son came out, we both sat there and cried,” Dan says. “You're going to love your child no matter what.”

“Marriage is a commitment that comes from your heart. If that person wasn't there, you're not going to be complete,” Dan adds. “If my son finds someone that he's in love with and wants to create a bond that's going to last a lifetime, that's marriage in my mind.” (The video is embedded on this page.
