But is religion the best way to reinforce these behaviors? And if it is bundled with other fundamental problems related to itself (possible false assumption that god exists, encouragement of outdated social norms, resistence to science/technological progress not because of the science, but because of conflicts with dogma and religious ideas, etc), then is religion even worth the effort?

I think some of what Dawkins was trying to get at was...religion ISN'T necessary, at least as far as morality in our culture is included. It's a tool. And if another tool can do the job better (or at least without as much baggage), then maybe we don't need religion in the role of 'moral authority' in the first place. Society will not crumble without it. Education, rehabilition, federal and state laws and penalties, civil lawsuits, media shame, and more secular methods seem to do the job too.
