You get no mileage out of that anymore . It's been way over played.
Here's a snip from sociologist Mark Regnerus study that was published in Social Science Research, Volume 41, Issue 4 July 2012 as it relates to children of gay couples:
"Although the findings reported herein may be explicable in part by a variety of forces uniquely problematic for child development in lesbian and gay families—including a lack of social support for parents, stress exposure resulting from persistent stigma, and modest or absent legal security for their parental and romantic relationship statuses—the empirical claim that no notable differences exist must go."
He found kids raised by gays have more problems than by straight parents. Now he doesn't make any claim that gays can't do a good job just that overall he found their kids had more problems. That runs counter to many previous reports and he explains why. Pretty common sense stuff if a person takes the time to read it instead of the attack machine that went out of control when he published the report. The thought police hit the melt down mode on this one.
So as vesper has been saying, a lot of thought should go into any gay marriage decisions. Marriage sets the standards for the family unit even though that unit has been under attack from the left as well for years already. Sorry ladies but single women usually make poor daddies. Not always, but usually. So now if we start adding even more strain on kids with gay parents, which the research shows higher numbers will have, what's tomorrow look like?
