Many are complaining that by reaching out to Rick Warren, Obama is offering a slap in the face to progressives. This is silly. Yes, Warren has badly screwed up views on social issues. Most Americans do. That doesn't mean they must be shunned or demonized; it means that we need to do more to engage with them and bring them to their senses.
No matter the strength of our first-order disagreements, we should be able to 'detach' from these and treat each other with respect. That was kind of the whole point of Obama's "new politics". For those culture warriors who are shocked, just shocked, that Obama can bear to associate with evangelical conservatives, or who see such expressions of respect as somehow undermining his first-order commitment to liberalism, I can only ask: weren't you paying attention? This is exactly what we want: a president who will advance solidly liberal policies, without demonizing or alienating conservative-leaning people. If we can leave off the tribalistic hating for just a moment, maybe some of 'Them' can even be brought around to our side.
