Is Good An Opinion?

So an atheist thinks good and evil is not a view point or opinion? To you the strong is not impose their goodness to the weak?

I'm very sorry to say that it appears you are losing this argument. First, atheism has nothing whatever to do with an understanding or recognition of good, evil, power, and weaknesses. Secondly, it seems that your argument boils down to the claim that what you and I call good and evil are merely opinions, somewhat akin to my opinion that the Cubs will win the pennant this year. If I kick you in the shins, it is more than likely that you will find that a less than good experience. Why can I conclude that having not even met you? The answer is simply because we share a common physicality from whence comes our understanding of goodness and badness and indeed taboos and traditions that stretch across cultures and over time-- not as an absolute but generally. The facts from anthropology, biology, and history do not support a theory of radical moral relativism.
