Theism and Moral Realism are separate concepts

The reason why is because of the old canard, Euthyphro's Dilemma. Let's remove language about "commands," though, and just talk about whatever the "good" is supposed to be.
If what God thinks and does is good because it is good, then "goodness" is a standard that's external to God that God just follows like the rest of us. It would mean that God had no part in defining or creating what "good" is, because if He did, then "goodness" as a standard would be up to whatever God's whim was when He created it, and that's the next thing that will be brought up. In this case, if moral realism is true (and there are "moral truths"), then God has nothing to do with them: He either follows them or He doesn't, he either commands that we follow them as well or He doesn't, but He had nothing to do with why they are there.
If what is good is actually good because God thinks it is good -- if God defines Goodness by His preferences -- then there is likewise no moral realism: there are no "moral truths," there are only preferences that God happens to have, and there is nothing about reality about why we ought to have those same preferences. One could argue, "you ought to agree with God's preferences because He's powerful and can cause you to suffer forever if you don't," but that isn't moral realism (that's "might makes right"). One could argue, "you ought to agree with God's preferences because God created you so you owe him," but there is a missing argument for why a creation must agree with the preferences of a creator (suppose Hitler were to create a truly conscious AI: does the AI have a moral obligation to agree with Hitler's preferences because he is the AI's creator? Prima facie I think you would agree that would be asinine).
God can have whatever preferences He has, but that wouldn't imbue all other sentient, conscious, sapient beings with the "ought" that they ought to have the same preferences. In such a scenario, moral realism isn't true at all: there are no "moral truths," only God's preferences. It can be true that God has preferences, but it wouldn't be true that we are compelled to agree with them. If God were to command that we smash babies upon rocks, it wouldn't be true that we ought to agree that is "good."
In neither scenario does theism seem to have anything to do with moral realism: either there are moral truths or there are not, but God's existence seems to have nothing to do with that dichotomy: they will happily go on existing with or without God, and God is either beholden to moral truths the same as the rest of us (if they exist) or not (if they don't).
Why, then, do so many theists claim not only to be moral realists, but that moral realism is dependent on theism? It can't be, even if it were true.
