“8% of the variance in sexual orientation is determined by genetics” is literally a quote from the study. I don’t have a personal viewpoint one way or another. I’m literally just reading the facts as they’re presented and saying “many types of variance exist.”

Obviously some people choose to be gay, Cynthia Nixon for example, who got in huge hot water for saying that for her, being gay IS a choice. She was specifically not “born that way.” Others clearly are. It’s a spectrum. :)
