I think you're last paragraph is exactly why the show didn't work for me dramatically (although I did enjoy parts of it quite a bit). Yes, I do agree that that is objectively wrong. So what are we learning? What's the show's message?
it paints the situation is if New Yorkers are the only ones that know this is inherently wrong. That by default, Midwesterners are ignorant and homophobic. I think that assumption is a bit isolating.
