我只做最简单翻译 没加个人意见
https://en.wikipedia.org/wiki/LGBT_parenting
Opponents of LGBT parenting have argued that it adversely affects children.
很多反同团体认为同性家庭对小孩有害
However, scientific research consistently shows that gay and lesbian parents
are as fit and capable as heterosexual parents, and their children are as
psychologically healthy and well-adjusted as those reared by heterosexual
parents.[1][2][3][4][5]
不过科学研究不断显示(consistently shows)同性家长不比异性恋差
小孩的身心法展也没比较差
Major associations of mental health professionals in
the U.S., Canada, and Australia have not identified credible empirical
research that suggests otherwise.[5][6][7][8][9]
美国加拿大澳洲的主要精神医学机构也没得出不同结论
光这一段就有9篇参考文献
有兴趣的或想反驳的可以看完文献再反驳
或者你拿出其他研究
