Well liberals aren't exactly known for sticking around. Look at the black community in America and its decline over the past 60 years. Cities and stated literally falling part under liberal leadership.
I'm not saying the same will happen with the gay community but liberals track record of exploiting the poor for their elitist goals is not a good sign.
Remember the purpose of liberalism is too fundamentally change something even if there isn't a reason too. The great liberal lion himself Kennedy once said the liberal dreams of a world that is yet to be, and he is correct that is what liberals do. So once they have fundamentally changed something it's on to the next fundamental change.
Persoanlly I think liberals should go after 2+2 next it has been equaling 4 for forever, it's time for fundamental change to come to 2+2.
