I strongly disagree with you. There was one prominent homosexual couple on the show and that couple served as an important plot device to make commentary on our society. There were plenty of heterosexual (and even robosexual) relationships that we’re just as “in your face”.
To me it always seemed nice to see a homosexual relationship placed on the same level as heterosexual relationships. I also thought it was a clever way to discuss homophobia through a lense of heterophobia and to discuss trans issues through a lense of forced transition.
