Interesting video, but I feel he (intentionally or unintentionally) mixed two things. When he talks about stuff worth taking from religion, I'd say there is the "message", i.e. the ideas, principles and rules of the belief-system, and then there's the "tactics", i.e. how you get a message out to the people and make it stick. The way I perceived it, he begins his speech talking about how there's good message that we can take from religion instead of simply rejecting it as dumb or backwards. However, he then starts focusing entirely on the tactics religion uses to spread its message.
As for the tactics, I agree that there's probably plenty of stuff that can be taken from the different religions for great effect. After all, the big world religions have had centuries to try out and refine their communication. Part of it is honest, putting the people in their quality as humans in the centre. Focusing on emotion rather than just abstract concepts. A big part, however, is also clever use of human psychology, sometimes with less, sometimes with more manipulative characteristics. I'm not generally opposed to employing stuff like sermons or group rituals when teaching morals. However, religion has an ugly tendency to suppress critical thinking and instead telling people to believe and obey. This needs to be avoided.
As for cherry-picking parts of the message, I'm not so sure. Unfortunately he didn't really give any examples on this side. I don't believe that we really need religion for a consistent set of morals, even though there are interesting concepts to be found in the different religions of this world. I think humanity would be better off on the whole if we took the plunge and abandoned religion as a source of guidance.
That said, I'm an atheist and I really like churches
