I guess it hasn't occurred to these folks that what they think doesn't matter one iota to the church as an institution.
The Catholic church has roughly 60 million adherents in the U.S. And I use the term "adherents" loosely. That's folks who identify themselves as Catholic. Perhaps half that number actually attend church on a regular basis. Anyway, of that 60 million Catholics, what percentage both agrees with the various outraged groups cited and is active and participating in the church? Maybe 1/10?
OK. So we're at maybe 6 million active U.S. Catholics who give two hoots and a holler what these groups think. And that's probably a very generous number. So out of a total of 1.1 Billion Catholics worldwide, we're talking less than 1%.
These groups are a noisy but very insignificant minority in the church. They could all choose to walk out the door tomorrow, and the church would make up their numbers in less than six months in Africa and Latin America. If they think they're somehow going to be able to "change" the church, they're deluding themselves.
Statistically, it can't even be that high. Most demographers put the entire Homosexual population at 10% of the total (although you'd think its everybody you see on the news because the media loves them), thats about 26M people. 6M would be a little more that 1/4 of that total as Catholics. I don't believe the number of Catholics that are Practicing Homosexuals is that high.
That's why I don't take the ones who sneer at the Episcopalians and Presbyterians too seriously. They've got their own attendance problems. They were just a LOT bigger to start with.
