Bollocks.
My friends are raising two orphaned sisters from a 3rd world hellhole. They are getting a wonderful life in a loving home.
If that's what you think is a decaying society, then you need to look in the mirror for decay.
Some of these folks don't have a clue about what they are talking about. None. They are just pounding the keyboard. They have no evidence, statistical, anecdotal, or otherwise. None of them know gay couples with children personally I suspect. None.
You'll have to pardon me, but I don't find it very impressive that people found it necessary to crawl over needy children in our own nation to save needy kids overseas.
It's become quite the rage to adopt from overseas. How about jumping in and giving kids from our own nation a happy home.
That would be my first objection. My second objection is that children do best when they have a male and female role model in the home. God didn't provide Adam and Steve or Eve and Eva. There was a reason for this IMO.
Now there are times when people have been exposed to kids from overseas through their life travels there, and they stepped in seeing a need. I would admit that could mitigate my comments in the first paragraph.
And one imagines that some of your best friends are blacks and Jews, too. Aren't you special?
