I agree with that being the first and greatest commandment, but it's for individuals. What do we do as a society when other people do not keep that commandment—or more relevantly, the second, to love their neighbor as themselves? Where is the line where we intervene for the sake of others?
Perhaps these problems can't be solved by society? The amount of misalignment of (putative) intent and effect in education I've seen, especially at the policy level, at least suggests this. If that's true, the question you should be asking is what should I do when other people do not keep that commandment.
Looking at the states still condoning corporal punishment, it seems those god-lovers spend all their love on god, and have only the stick and paddle left over for their neighbors and children.
This will solve the problem on every level.
