Having same-sex parents doesn't affect a child's sexual orientation. Children may be more likely to experiment with same-sex relationships, but are no more likely to identify as lesbian or gay as adults.
Statistics show that conception via a donor's sperm or egg has absolutely no impact on the relationship between parent and child, as long as children are told before they go to school. If they find out later, they can feel deceived and lose trust in their parents.
Children don't suffer from lacking a male or female parent, and there is no evidence that it affects masculinity or femininity.
It's prejudice that causes problems for these children, not the families themselves. While people have the right to their own beliefs, they can't argue that these families are worse for children - 40 years of research has proven this is not the case.

I was always making notes on scraps of paper about tips and facts I'd read in books and magazines, seen on the Internet or on TV. So this is my paperless filing system for all those bits of information I want to access easily. (Please note: I live in the UK, so any financial or legal information relates only to the UK.)
