Warning: If you want to watch a talk about whether or not homosexuality is biological or learned, don't watch this. This is about how to be a christian and preach to gays and lesbians. This isn't about homosexuality or public policy, it's about religion. But if I want to get information about whether or not homosexuality is an innate or learned sexual preference, I'll discuss it with a biologist rather than someone with a PhD in english literature or cultural studies. But this talk is about religion and sin, it has nothing to do with biology.
You just don't like her because she is an Ohio State Buckeye! - Ah, the root objection! This clip is about religion (or relationship would be a better description), and it is about a lesbian who is now married and in a perfectly healthy heterosexual relationship. Do I personally believe that a conversion to Christianity had a huge impact on her being able to finally "alter" her choice - yes! However, if you really listen to this with an open mind, she actually was headed that way "before" her conversion. It is also about how to relate and respond to those in the homosexual community in a loving, caring, friendly, and compassionate way and not a self-righteous, Pharisaical way!
You cannot seriously research the "studies" on homosexuality and genetics and arrive at the conclusion that it is an "inescapable" condition attributed solely to genetics, and those are biologists and genetic researchers. The point is that this women or men, whether religious or not (which seems to belie your implied disdain for religion), can change and this is a case where a woman was able to "escape" or change her gender "identification". I suppose someone could just choose on their own. However, the press and many in our country would have you believe that it is an "inescapable condition" and that you have no choice and that society "discriminates" against those that have no choice. If you really want to read about this in an objective manner, read a book (if you dare!) called Homosexuality and the Politics of Truth by Dr. Jeffery Satinover, a Psychiatrist (a Jewish doctor and non-Christian) on the studies. You can also read the findings of Dean Hammer (which showed a zero concordance rate among females). Or take a note of NPR: http://www.npr.org/templates/story/story.php?storyId=1048788 Anyway, the point is NOT religion or religious conversion necessarily (even though this author believes that it can play an enormous role in correcting false, preconceived notions bantered about by the media and other entities, and heralded by other entities that are ignorant of facts and just accept the "drool" offered by those groups without question).
As I've discussed with you in the past, I think there are certainly those that are born with a predilection to be homosexual. I also think some people aren't but have life situations that foster homosexual behaviors. My guess is that she is the latter. Also, for every case like hers I'd imagine there are many more that wish they could be heterosexual, because of societal pressures, but cannot be, because they aren't. cgod's comment below sums up my thoughts pretty well on the subject, which is why I badged it.
And, oh by the way, I believe this clip shows a very compassionate way for folks to address the homosexual community instead of just saying, "Brother or sister, if you continue to practice homosexuality, you are going to "bust hell wide open". This is NOT the way to address people of this choice, and it is SELF-RIGHTEOUS to do other than this gentile way of relating to the homosexual community.
