As if no one could have predicted it, the largest study to date of adult children of same sex couples shows that they suffer poorer outcomes than adult chidlren of traditional couples. This would be a big "Duh" except the Gayhaddis kept quoting small selective studies that showed the opposite. But politicized science and small samples are no match for a broad wide range study. And the results are just what you would expect.
Cue "bigoted Texans"meme in 3...2...1....
Adult Children of Parents in Same-Sex Relationships Report Varied Outcomes
Some interesting results there. However, I think that the stigma of being gay was significant enough for the majority of the lifespan of the respondents that their lower socioeconomic status is most likely derived from that fact. If you can't get a good job because you're gay or lesbian, you are going to be forced to take Public Assistance in many cases so that result is neither surprising, nor concerning.
The other effects though I can see and that is no doubt due to parenting styles rather than sexual preference. But, not having seen the actual study, I am merely postulating.
