My deepest hope for tomorrow is that we listen to one another, and that we hear one another. We can put our best efforts forward, but only if we battle one another less and respect and listen to one another more (even through some real disagreements). The meeting will be much more effective if we are not so locked in to our positions that we cannot hear and appreciate what the other is saying.
I've been working in and around LGBT marriage campaigns for nearly a decade now, both as a volunteer and as full-time staff. And I know one of our tendencies as LGBT people--a group that has had a rough go at it--is to strike out against one another, rather than focus on who our real opponents are and operate under the assumption that we are all doing the community's work in the way we each think is best.
