I want to put in a plug for some good background reading.
United Families International has several detailed, documented guides on family issues like abortion, divorce, and the advantages of marriage. They are a good read to get some facts and understand (and refute) the arguments used by the other side.
I would recommend starting with the Sexual Orientation guide that confronts 22 myths about homosexuality and provides 145 "Fast Facts" about the issue.
Happy reading!
