I don’t really have a stance in the girl personally as we don’t even know all the particulars. I’m not entirely convinced it’s about her sexuality.Valid points you shared, and I'm not disputing your analysis.
I think the issue is more of an emotional (not legal) one. I'm straight, and can't relate to the girl's sexual identity; but I do have a heart, and just feel bad for any child struggling with certain situations.
The bigger point that I’m getting at is traditional religion in the US is always or nearly so going to be at odds with the LGBT community. It should come as no surprise that’s the case with this story.
