On April 4, 2013 the National Committee of the Social Democrats USA passed the following resolution in support of marriage equality, to strengthen its general support of the human rights of LGBT people.
Resolution on Marriage Equality
Social Democrats USA seeks to build a society that affirms the worth and dignity of every human being. We pursue the values of freedom, social justice and human solidarity not only for the distant future but in our immediate and current activities. The many forms of oppression experienced by LGBT people offend the values that we cherish; we support efforts to end all forms of that oppression and to include LGBT people in all aspects of our society, including marriage.
