Do you think there will ever be a time when the U.S. accepts gays as equals and allows them to marry just like everybody else?

The governor of New York just passed a bill into law allowing gay people to marry. This will be the 6th state in the U.S. to do this but there is still a lot of controversy with this topic and a lot of hate toward gay people. Will this be a continuous battle among Americans or will there actually be a time in which married gay couples will be just as common and accepted as straight married couples? If so, do you think we are even close to that time or will it be decades before it happens? What opinions do you have on this topic?
