Just like California, gay couples tasted the fruit of being able to marry like everyone else, and it has been pulled away. . The reason why is because the U.S. Supreme Court has just put a hold on same sex marriages in that state, pending the ruling of an appeal to a federal appeals court. (Of course in California, such a ban was completely overturned.)
Late in 2012, a federal court had struck down the bans on same sex marriages in Utah as a violation of the U.S. Constitution. But the possibility exists, if the federal appeals court rules for marriage equality, that there could be a the next couple of years (if not sooner) a monumental ruling by the highest court in the land.
If so, those opposed to marriage equality in Utah will regret their appeal of this ban in Utah. But since Utah (and the Mormon church) has been a state that has bankrolled efforts in other states (California successfully for a while) to ban same sex marriages, it would be richly ironic if it was the state and its' appeal that led to marriage equality in all 50 states.
Lastly, as I have said before you can support marriage equality by supporting the Human Rights Campaign and Freedom to Marry. Thanks.
