What's the most persistent myth about being raised by gay parents? "That you are a child abuse victim," says Zach Wahls, author of the new book, My Two Moms: Lessons of Love, Strength and What Makes a Family.

Wahls became an internet sensation after a video of him defending his mothers' same-sex marriage was uploaded to YouTube. His 2011 testimony before the Iowa House Judiciary Committee has racked up over 18 million views and led to appearances on The Daily Show, Letterman, Ellen, and many other places.

Now comes My Two Moms, in which the 20-year-old University of Iowa engineering student explains what it's like to grow up as a child as the child of same-sex parents and uses the lessons he learned as an Eagle Scout to talk about why marriage equality should be the law of the land.

Wahls sat down with Reason.tv's Nick Gillespie to discuss why his childhood was a lot like yours, the mainstreaming of same-sex marriage, and Obama's "evolving" views on the subject.

About 7 minutes.
