Most people want to say that it is not a marriage because a marriage is a pact between a man and a woman, and that allowing same-sex couples to participate in it it would be something completely different (10 reasons to be homosexual). This reason here is also mainly based on the Bible, because it says: Ephesians 5:25 Husbands should love their wives, as Christ loved the church (KJV). Giving people the interpretation that it only means one man and one woman. However, it also says that love is patient, love of its kind…love never ends (KJV, 1 Corinthians 13:4-10). Saying that no matter who they are, they deserve love.
