I don't quite understand why people put so much time and effort into conversing with other people about their internal "belief systems." To me, the only thing that really matters is how other people behave: whatever they believe is secondary to how well or how poorly they act. If one person believes "treat others well because Jesus says so," while another person believes "treat others well because Krishna says so," wouldn't they then both agree with each other that the over-riding priority here is to treat others well? How much "should" it really matter WHO says so?

Your view reminds me a bit of what used to be called "Christian atheism". The idea was that to say for example that God is our heavenly Father is to adopt and proclaim a policy of behaviour towards other men, namely one of brotherhood. The problem with ruling out religious faith as such, "without works", so to speak, is that as a matter of fact for many if not most religious believers it is not the case that religion is just ethics and that "the only thing that really matters is how people behave". That may be what matters to you; then you are saying, 'Ethics matters to me; religious faith doesn't.' And if your view is stated impersonally, that the one ought to matter and the other not, we have to consider the fact that it might be the case that people came to be behave in a brotherly way, but without any affection or love. Would that be as good as people behaving well towards one another and loving their neighbours? And that is the heart of the matter. Behaviourism (your view) is I am afraid to...
