Homosexulity is a minority that is part of the normal range of human variation. With a prevalence somewhere between that of being Jewish, and that of being Native American in the US population. Ana Bray---if you look at her---is clearly someone who is of "Amer-Asian" descent. Yet no one insists that her benig part Asian is "forced diversity" and need to JUSTIFY its existence. Ikora Rey is African-American...and no one is saying (openly) that her being Black has to "justify" its presence in the story and her being in a position of leadership and responsibility doesn't "reflect life". Oh and Destiny does imitate Life in that Guardians have been pulled from the full range of the human family. Not just Europeans. Straight people or men.
