If the show's writers truly want to examine how tolerant the two homosexual characters are they should introduce yet another 8-year-old: One with strong religious values and an NRA membership card. Let's see how this would play out ...
The NRA character would be portrayed as a hateful, intolerant Republican Trump-Supporting bigot, and would be the butt of every joke. Mid-season, they'd have a "Very Special Episode" where he shoots up a school/minority-run church/Democrat Political Rally.
Consumed with grief, the character reaches deep within himself only to discover that he's Gender Fluid. He begins both male AND female hormonal treatments (hahaha!) and begs forgiveness from his family (really the viewers) for his transgressions.
The season ends with the NRA character living in a commune and engaged in a polyamorous relationship. They petition the Courts to change the law so that their entire group can get married....and that's the cliffhanger.
