By all means, commend the Mormons for stepping up to the plate on Prop 8. Still, the figures I saw is that they gave about $15.4 million out of the $35.8 million raised...42%. Hefty? (Yes) The majority? (No. I mean how many candidates who garner 42% of the vote can claim a "majority" win?)
Lest you forget, many Evangelicals/Protestants consider their Catholic and Orthodox brothers as coming under the same universal umbrella of a certain faith called "Christianity." Now did the other 58% come from this umbrella? Well, I'm sure some of it came from those who claimed Judaism, Islam, and even atheism. But I would "wager" that over 50% came from those with ties to traditional Christianity.
So, tell me again how that "leads Christendom in a very public campaign?"
Also, such a campaign is NOT only about the $ contributed. It's also an "air" game of relating to the public and the "ground" game of getting out the vote. LDS is only about 2% of CA; its CA ground game had natural limitations. So no matter what you think, LDS did not "lead Christendom" in the "air" or "ground" game in getting Prop 8 passed.
In your zeal to slap down any positive comments about Mormons, you overlooked the facts in your own post. Mormons are 2% of the population of California, but they gave 42% of the pro-Prop. 8 money.
They were also vastly overrepresented among those doing the volunteer work to pass Prop. 8.
