Currently, 13 states recognize marriages of same sex couples that are legally performed in other places.
The most recent is California. California briefly allowed gay marriage in 2008 until something called Prop 8 stripped same sex couples of this right. Prop 8 was repealed in 2010, and in June 2013, it was found to be unconstitutional, allowing gay marriage to resume in that state.
Shortly before that, in April 2013, Rhode Island made gay marriage legal.
During the 2012 Presidential election Washington, Maine and Maryland became the first states to approve same-sex marriage by popular vote. This was a pivotal and telling moment since going into the election, gay marriage was legal in six states and Washington D.C., but each of these was the result of legislation or court orders, and not by a vote of the people.
The passage of gay marriage in New York, in June, 2011, has been seen as a pivotal event. New York is America's third-most populous state and same sex marriage was passed in that state by the elected legislature and not through the courts. It was also voted for by Republican senators.
Same-sex marriage has also been legal in Massachusetts since May 2004, in Connecticut since November 2008, in Iowa since April 2009, in Vermont since September 2009, and New Hampshire since January 2010.
Additionally, in June 2013, the Supreme Court of the United States overturned DOMA, the Defense of Marriage Act. Since it was passed in 1996, DOMA banned same sex marriage on the Federal level. Overturning DOMA allowed any same sex couple married in a state or country where gay marriage is legal to have their federal rights recognized as a married couple in the United States. These include things like federal pensions and tax and inheritance benefits.
Each of these fights has been important in their own ways and with all the talk of gay marriage, it is little wonder that GLBT teens have a lot of thoughts on the topic. Here's what some of them have to say.
