Atheism and Ethics

[Angrboda]

Are you suggesting that people assess choices with moral implications based on utility rather than right and wrong?  That doesn't seem sensible.  Even if they take into account utility, they still have a reason to behave morally, even if they don't do so.  The other does not which leads to purely situational ethics.

No, but I am arguing that sometimes utility will win out when facing a hard decision or strong emotional inclinations. It is possible to think something is wrong and still do it, in fact I think it is common on some of the “smaller” things
I just don’t believe people think through consciously why they do a lot of things, they just do them

Re situational ethics - are you saying that that is what the anti-realist has?

That's a semantic question. From a practical standpoint, an anti-realist makes choices which have a moral dimension situationally. I don't think it matters whether that dimension is real or not.
