In a project launched last month, a team I direct at Columbia Law School has collected on one website the abstracts of all
peer-reviewed studies that have addressed this question since 1980 so that anyone can examine the research directly, and not rely on talking heads or potential groupthink. Even when we might not agree with a study’s conclusions—with how a researcher interpreted the data—we still included it if it went through peer review and was relevant to the topic at hand. Peer review, of course, isn’t perfect, but it’s one of the best ways the world has to ensure that research conclusions are at least the product of good-faith efforts to get at the truth.
The Columbia project is the largest collection of peer-reviewed scholarship on gay parenting to date.
What does it show? We found 71 studies concluding that kids with gay parents fare no worse than others and only four concluding that they had problems. But those four studies all suffered from the same gross limitation: The children with gay parents were lumped in with children of family breakup, a cohort known to face higher risks linked to the trauma of family dissolution.
Even the notion that you try to put forth that there are no good studies is wrong...the studies, while not perfect do give us a very good idea on the conclusions and that is that gay homes are not better nor worse.
Here is a link to all the studies

I should add, the consensus that kids in gay homes do just as well as kids in straight homes is recognized

Consensus
The scientific research that has directly compared outcomes for children with gay and lesbian parents with outcomes for children with heterosexual parents has been consistent in showing that lesbian and gay parents are as fit and capable as heterosexual parents, and their children are as psychologically healthy and well-adjusted as children reared by heterosexual parents,[3][4][5] despite the reality that considerable legal discrimination and inequity remain significant challenges for these families.[4] 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] Literature indicates that parents’ financial, psychological and physical well-being is enhanced by marriage and that children benefit from being raised by two parents within a legally recognized union.[5][6][87][92] Statistics show that home and childcare activities in homosexual households are more evenly split between the two rather than having specific gender roles,[93] and that there were no differences in the interests and hobbies of children with homosexual or heterosexual parents.[94]
