The defense of marriage act should be replaced by an act to allow anyone to marry anyone else as long as all parties to the marriage freely consent and are of legal age and sound mind.
Marriage should not be limited to one man and one woman.
Gender, sexual preference, race, and religion should not stop people from marrying if they wish to do so.
The government should also not tell people how many people they may marry. As long as all parties agree, if three woman want to marry each other, good for them. Two woman and a man, wonderful.
Let people choose who they want to love and spend their life with, it isn't the business of the government.
Right now many people in the USA are in homosexual or poly relationships and are robbed of their rights based on centuries old prejudices.
