I can
Eunice and Owen Johns, Christians, were turned down because they are anti-homosexual based on their interpretation of the Bible.
Short news clip
In the clip Eunice says to tell someone it's OK to be gay would compromise her faith and as a non-discriminatory policy is part of the foster parent agreement she and her husband cannot adopt.
She seems to think children only become homosexual after the age of 10 so you should be allowed to adopt up to that age. Bizarre.
It is said near the end that Eunice and Owen withdrew their application but are at liberty to reapply.
Strictly speaking it's not because they are Christians but because the insist homosexuality is "wrong".
I assume they think it's a sin and such a child or adult will be sent by their loving god to Hell and burn forever. Not really symptoms of a health mind and fit people to foster.
If it's not this exact case I'm willing to bet it is a similar one or one no better.
If this is the case BR refers to it does have his usual lack of comprehension, exaggeration, spin and misrepresentation.
