In my prior post, I argued that the primary argument for why same-sex marriage should be legalized–“it is discriminatory to tell consenting adults who love each other that they cannot get married”–is fatally flawed. On the logic of this argument, virtually any kind of marriage could be justified, including polygamous marriage and incestuous marriage.

In one of the comments on my prior post, there was a link to a fantastic video of Ryan Anderson speaking for the Heritage Foundation.  He makes precisely this point and utterly dismantles the argument that denial of same-sex marriage is discrimination.

What is particularly stunning is that the man asking the question in the video is totally unaware of the inconsistency of his argument. Indeed, he just talks in circles, unable to provide a coherent answer to the very simple question of why homosexuals should be granted special rights, but not polygamous or incestuous couples.

When you listen to this exchange, it becomes excruciatingly clear that the debate over same-sex marriage in this country is not being decided (by most people) on the basis of reason or logic. But on the basis of emotion and cultural pressure.

This video is short (4 minutes) and worth a careful listen:
