I'm a moral anti-realist, but that doesn't stop me from acting according to my morals. Much like existentialism doesn't stop you from creating internal meaning to life moral anti realism doesn't stop you from having moral opinions. Just because moral statements aren't facts doesn't mean I don't get utility from acting on my chosen moral preferences. In fact, in a non-spiritual world there is no reason for realists and anti-realists to behave differently at all. If there aren't consequences for behaving immorally the only reason to do so is because of how it makes you feel.
