Perhaps learning that his son is gay forced Portman to rethink his views about gay people, leading him to question things that in the back, or front, of his mind he had believed: that being gay is a lifestyle choice, that gay people are unfit to raise children or that they are not capable of establishing enduring loving relationships. However, believing these things today can only be the product of a mind that is deliberately closed to the mountains of scientific, personal and anecdotal evidence around us. In fairness to Portman, and conservatives generally, many progressives had also been notably silent on marriage equality until very recently.
