A lot of what Veg said has common sense. She agrees that homosexual fostering and adoption has risks. Her sister's situation seems safe. I would accept that. Maybe the problem is men. Males who are either single or in same sex relationships shouldn't adopt in most cases. Because they don't have the moderating influences of women in their lives. Single people can adopt but I don't think regular men should be adopting girls and I don't think homo men should adopt boys. Exceptions might include when a long term common law partnership sees the woman die and her daughter has no one and sees the man as her dad. A little flexibility is in order.
So why do I see lesbians and homosexuals differently here? Partly because the latter, being men I see as more sexually aggressive. And my personal experience verifies that. And of course as an enlightened renaissance man and reformer, I have a soft spot for fallen women. (Just kidding.)
As far as the treatment of Mr Coatrail goes, I think he brought it on to himself as tag points out.
