I for one am ambivalent. The foster homes are often filled with children who are not given sufficient care. I don’t think we should hold their belief that homosexuals are sinners against them as much as find out what they really think about gay people. A lot of people don’t like gay people but are capable of showing affection to them. They may turn out to be really really good at it.
There are shades of homophobia which range from burn in hell to mere distaste. People can change, much as I despise their viewpoint they deserve the chance to change and they have proven to genuinely care for children.
