An old anti-Catholic tactic of bad journalism
GetReligion (of course) describes the game:

A reporter writes about a controversial cultural issue such as contraception or abortion. Opponents are identified by their religious denomination. Supporters are not. The lesson for readers is plain: opponents are motivated by religious zeal, while supporters are motivated by humanitarianism and sweet reason.

When the media do things properly GR gives credit:

Gay rights and religious freedom
It’s the crybaby a**holeness of the anti-freedom left that offends me, not that some people are in relationships that make no sense according to the Catholic faith and natural law (don’t mind if you do)
