I can't adopt - I'm gay

Not true

There is nothing in law that prevents gay people from adopting children.
However adoption agencies can make subjective decisions about a person's suitability based on lifestyle. And in many cases public pressure means that homosexuals, whether single or in established permanent relationships, may find it harder to be accepted by an adoption agency.

However, changes are afoot. In 1999, a leading national adoption agency, The Children’s Society, changed its policy on homosexual adopters.
And Dame Elizabeth Butler-Sloss, the head of family courts in England and Wales, threw her support behind gay couples who wanted to adopt children.
She said: "It would be quite wrong when looking at the welfare of the child
not to recognise that different children will need different types of parents."
The government however is expected to change the law in the near future to give equal adoption rights to all un-married couples. This would include gay couples.
