I didn't suggest an amendment to allow gay marriage, I suggested an amendment that would explicitly prohibit the state and federal governments from attempting to regulate any marriage between two consenting adults. In an academic manner, you are right. Its silly that we have to do anything to keep any government from interfering with things that we consider to be fundamental rights. I didn't suggest that the constitution mentions marriage. However, its failure to explicitly state it as a fundamental right is a large part of the reason gay people were oppressed for so long in our country. Historically, rights not outlined in the constitution fall under the authority of state governments. Also note that the constitution and the bill of rights are more of a statement of rights we already have. The document isn't intended to actually grant the rights. No one can grant fundamental rights. However, having a constitution as a statement of rights can help protect them when others want to take them away.
