I actually think a "don't rush into marriage" message might be valuable. The Eastern Bloc went through a lot of social problems when they woke up and suddenly had democracy and free markets; Russia's still dealing with that legacy. And Booker T. Washington's "Up from Slavery" brought up what he at least perceived were problems resulting from sudden emancipation. I'm gay, a POC, I think it's worth discussing, especially among an audience that's likely already part of the choir, as it were.
Thank you for your message! You’re right, it’s A) Not really fair for me to complain about Glee being awful before it does something awful. I have no real idea how the story’s going to unfold. B) Not really something I am educated or knowledgeable enough to address, especially from my limited perspective.
