The reason I say what I do is because it's the liberal progressive churches which are failing faster then Solyndra after an Obama Bailout, losing members at a startling rate for proof see this article from the Blaze, ‘Cross-Dressing Clergy’: These Are the Reasons the Episcopal Church Could Be Near Collapse, there are a few more but that make all the points in one article. But you can also look for the Book; Exodus Why Americans Are Fleeing Liberal Churches for Conservative Christianity, for even more on the subject.
Now to the point of her post, losing a generation, this generation (those under forty, which am in) isn't being lost, for those who believe its antigay not to allow gay marriage that is unfortunate, but many of that generation fail to understand the Truth, And I go to Genesis 19:4-5 for proof, 4. But before they lay down, the men of the city, even the men of Sodom, compassed the house round, both old and young, all the people from every quarter: 5. And they called unto Lot, and said unto him, Where are the men which came in to thee this night? bring them out unto us, that we may know them. And in Genesis 19:8. Behold now, I have two daughters which have not known man; let me, I pray you, bring them out unto you, and do ye to them as is good in your eyes: only unto these men do nothing; for therefore came they under the shadow of my roof. Why offer his daughters who "have not known man" if it wasn't about sex and in this case gay sex.
To deny that God created Man and Woman to be one it unfortunate, and what makes it even more unfortunate is these people claim we are misinterpreting God's intent but gods intent is clearly spelled out in His book the Bible.
Update; I have found a few links that should add to my argument and disprove the positives of gay parenting.
First on the gay parenting, http://www.foxnews.com/opinion/2012/06/12/study-finds-host-challenges-for-kids-gay-parents/
Next one that's a bit more concerning for us Christians in the long run, http://www.huffingtonpost.com/johann-hari/the-strange-strange-story_b_136697.html

If gays wish to be left a lone will give it to them (unlike the islamists) but don't try to force what you want down our throats. That does not mean you'll get gay marriage by the way.
