The largest study carried out looking at young adults who were brought up in a homosexual marriage was carried out by D P Sullins
It showed that the rates of mental health issues in kids brought up in a SSM sky rocketed in this population and that earlier studies on children in same sex marriage that had positive outcomes These studies carried out in the younger cohorts had systemic issues of bias
The results of homosexual families as a social engineering experiment certainly mimic the homosexual community at large in that it does not promote human flourishing
We should not be advocating or promoting SSM. Like we do not promote other harmful lifestyle choices such as smoking or drug use.
