[Disagreeable]

I'm saying that there's no agreement.

You're wrong about that.  Just wildly wrong.  Objectively speaking.  

Indeed.

You're wrong about that.  Just wildly wrong.  Objectively speaking.  That may not certify that moral realism is true - fundamental intersubjectivity is a strong possibility....but, like any number of failed (attempted-alleged-purported) assertions of fact....it's just plain wrong.

OK, then how do you explain the fact that for any given moral precept, some humans will say that it's right and others will say that it's wrong. That doesn't sound like agreement to me.

If two people both think that rape is wrong then that's agreement right there. Obviously there is some agreement. But you have said before that all we have is what's fashionable. So you're just discounting the agreement, but you haven't actually given an argument, you've just begged the question.

It's true that there is plenty of agreement

So there is agreement, then. So it makes no sense for anybody to keep pretending like there is only disagreement and no agreement. And if the agreement somehow doesn't count: why not?
