sartorias and rachelmanija have an essay in Publishers Weekly that they would like you to read:
"An agent from a major agency, one which represents a bestselling YA novel in the same genre as ours, called us.
"The agent offered to sign us on the condition that we make the gay character straight, or else remove his viewpoint and all references to his sexual orientation."
If you read all the way through, you will find suggestions for what you can do.
