我只做最簡單翻譯 沒加個人意見
https://en.wikipedia.org/wiki/LGBT_parenting
Opponents of LGBT parenting have argued that it adversely affects children.
很多反同團體認為同性家庭對小孩有害
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]
不過科學研究不斷顯示(consistently shows)同性家長不比異性戀差
小孩的身心法展也沒比較差
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]
美國加拿大澳洲的主要精神醫學機構也沒得出不同結論
