Image via WikipediaMassachusetts Attorney General, Martha Coakley, has filed suit with the US government for interfering with her state's sovereign authority to define and regulate marriage. This effectively questions the constitutionality of DOMA. DOMA states that no state (or other political subdivision within the United States) needs to treat a relationship between persons of the same sex as a marriage, even if the relationship is considered a marriage in another state.
Personally, I do not think that it should be left to the states to determine who is allowed to have the privileges of marriage any more than it should have been left up to the states to determine who is free and who is a slave. Without the freedom to enter into a loving union of two adult people, we are, in fact, slaves.
This is a matter that has to be determined on a federal scale. The constitution guarantees separation of church and state and protects us against taxation without representation. If churches want to effect law, they should be subject to taxation, just like the rest of us. Gay couples today do not receive equal protection under the law. Same sex couples who are married in states that allow it are not given federal tax breaks that opposite sex married couples receive. This is not equal protection under any law.
