I am of the opinion that too much political energy is wasted obsessing over morality topics like abortion or same-sex marriage. Seeking agreement on those issues is a futile waste of time, so I say leave the status quo in place (i.e., I don't tell you what to believe regarding those topics, and you don't tell me) and turn our efforts to more important and more resolvable issues.
I'd rather us focus on economic justice for those already born, the human rights of those already born, an environmentally healthy planet that we and our descendants can live with, education, scientific progress, and sane international diplomacy that actually promotes peace. (Although I suppose some might argue that those issues are equally resolvable and therefore equal wastes of time. )
