Here's a short answer that explains why civil union is second-class marriage for second-class citizens.
Civil union grants fewer rights, benefits, and responsibilities than marriage does.
E.g.,
* [Q] If my partner and I enter into a civil union in Vermont, will the government recognize it for immigration purposes?
[A] No, a civil union conferred by the state of Vermont is not recognized by the federal government, which oversees immigration.
[Q] Can I marry my same-sex partner in the U.S. so I can change my status to legal permanent resident?
[A] No. A federal law, the so-called "Defense of Marriage Act" (DOMA) passed in 1996, states that the federal government will not respect same-sex marriages. Therefore, even when states begin to end their discrimination and allow same-sex couples to marry, marrying a same-sex partner in the U.S. will not affect immigration status until DOMA is repealed or deemed unconstitutional by the courts.

* [Q] Will the Federal Government or Other States Recognize a Vermont Civil Union?
[A] The federal Defense of Marriage Act (DOMA) specifically states that the federal government will not recognize a same-sex relationship treated like a marriage. This means that, under the current law, parties to a civil union will not be able to qualify for any of the benefits and protections contained in the 1049 federal laws affecting the spousal relationship.
