Here’s US marriage expert Ryan T. Anderson giving one of his sparkling clear presentations on the problem with same-sex marriage. If you want to see how you can talk comfortably to your friends and family about the importance of preserving marriage, watch this video.

It’s nearly an hour long by Ryan’s presentation takes the first 23 minutes – and it’s worth every minute of your time to listen to him.

His bio – just to refresh your memory:

Ryan Anderson is co-author, with Princeton’s Robert P. George and Sherif Girgis, of the acclaimed book “What Is Marriage? Man and Woman: A Defense” (Encounter Books, December 2012). Justice Samuel Alito cited the book twice in his dissenting opinion in the Supreme Court case involving the Defense of Marriage Act.

In addition to a memorable 2013 debate about marriage on CNN’s “Piers Morgan Live,” Anderson has been the nation’s most valuable traditional marriage advocate, appearing on CNN, Fox, MSNBC, The New York Times, Washington Post, Wall Street Journal, and countless others.

Anderson, who joined the leading Washington think tank DeVos Center for Religion and Civil Society in 2012, also is the editor of “Public Discourse,” the online journal of the Witherspoon Institute. He researches and writes about marriage and religious liberty as the William E. Simon Fellow at The Heritage Foundation. Anderson’s recent work at Heritage focuses on the constitutional questions surrounding “same-sex marriage.”
