On Gay marriage and Obama's 'evolution'

I'm delighted that Obama cited the Golden Rule as one basis of his decision. What strikes me more than anything is the volume of Scripture that people have to ignore in order to justify actively opposing Gay Marriage. If the Gospel teaches us anything its that 1: Our responsibility is to keep our own House in order and concern over condemning others is itself sinful. 2:Prayer should be a private matter between you and your Creator and that public displays of piety count for naught. 3: We are ultimately judged by how we treat prisoners and beggars and outcasts. Engaging in behavior designed to create outcasts is directly contrary to Jesus's direction. It never ceases to amaze me how many people fail to notice these simple points.
