I think people were taking umbrage at forcing a homosexual into a heterosexual marriage. That said, those same people seem to be unable to distinguish between a plot twist and a political statement.
We were very anxious about, in the same episode, we revealed that Sara’d had this lesbian relationship, she also is sleeping with Oliver again and we really wanted to approach it, not be salacious and be sensitive and be realistic and actually, we specifically avoid using the term bisexual. We didn’t want to label her at all.
Let her be her own person and if the audience wants to label, fine, but we wanted to not make it like it’s that specific.
