Gallup's Values and Beliefs Poll, Catholics and Same Sex Marriage

Several Catholic friends have pointed out in recent days that our fellow Catholics continue to cave to the popular culture on the issue of same-sex 'marriage.'  They cite these statistics from the Pew Research group: 

Catholic respondents were slightly less likely than other Americans to oppose same-sex marriage. In 2004, 55% of Catholics were opposed, and 28% strongly. By 2012 those figures had dropped to 42% and 17%. 

As a rejoinder, however, there is the result of yesterday's marriage amendment vote in North Carolina as well as this recent Gallup Poll which says that more people are opposed to same-sex 'marriage' this year than last (48% vs. 46% respectively) or, conversely that there is slightly less support this year with 50% of Americans supporting same-sex 'marriage' as opposed to 53% supporting it last year.   And, read here.

I realize this doesn't address the Catholic problem per se, but at this late date why expect Catholics to behave any differently than the general voting public?  Catholics have succumbed to the sexual and social revolution of the 60s just as nicely as everyone else. Secularized and relativized, they voted handily for Obama in 2008, and, anecdotally, I know plenty of Catholics who will vote for him again. 

I read somewhere that Americans are great believers in fairness (just maybe something to do with our founding principles?), and I think that a good percentage of the so-called support for same-sex marriage comes from a desire we Americans have to be fair to our neighbors.  Notice that Gallup asked participants if same-sex couples should have the same "rights" as those in traditional marriages.  Rights?  Not only fairness, but political correctness dictates that we deny no one their "rights!"  And, actually, some of the things same-sex couples want could and should be handled with changes to the tax code.  By phrasing their question in terms of rights, Gallup is being just a little disingenuous with this poll.

If, as Gallup says, this poll is part of its annual Values and Beliefs poll, why didn't they poll people as to what they believe about traditional marriage and what they believe about same-sex 'marriage?' Why didn't they ask people if they are teaching their children that same-sex 'marriage' is the same as traditional marriage?  Why didn't they ask people if they believe sex education in the schools should teach that homosexuality is normal? Why didn't they ask people how they would feel about having a daughter-in-law who is a husband or a wife to their daughter? 

Gallup headlines the article, that half of Americans support 'gay' marriage.  That also means that half don't support it, a little detail that could just as easily have been the headline of the article.
