‘Catholic Church officials still dither and wring their hands over whether...same-sex couples are living in sin, a matter long settled in the minds of most American Catholics.’
1. I would hope Church officials (=bishops?) are not dithering but answering with a simple, ‘Yes, they are living in sin.’
2.  We all live in our little bubbles, and it’s possible that in the author’s bubble most people have ‘long settled’ the question in her favour.  But she might be surprised if she visited other bubbles.  And ultimately, does it really matter what ‘most Americans’ think?  Can that change what’s right or wrong?
3.  The strident tone of this article—indeed, of many NCR articles/editorials—is not helpful not conducive to true dialogue.  Indulging in phrases like ‘homohatred’ to describe people who hold diverging opinions only debases the author’s credibility.
4. I don’t know anyone who is against ‘same-sex love’.   It's the eroticisation of such love that's the sticking point.
