One prominent example is a paper by Baylock (arXiv:0902.3827). Baylock thinks that counterfactual definiteness is one of the minimal assumptions behind the derivation of Bell's inequality. But Baylock's attempt to show exactly how Bell's supposed assumption of counterfactual definiteness led him astray, so that there can be a local explanation of the violation of the inequalities, is incomprehensible. You equate 'realism' with counterfactual definiteness. That means, of course, that quantum mechanics is not a realist theory -- which is a rather extreme view, given the empirical success of the theory. To claim that it does not represent reality is a rather absurd claim. Maudlin (arXiv:1408.1826) points out that it has become fashionable to say that another way to avoid Bell's result and retain locality is to abandon 'realism'. I think you have said much the same on occasion. Maudlin goes on "But such claims never manage to make clear at the same time just what 'realism' is supposed to be, and just how Bell's derivation presupposes it." I think it is better to stick to the commonly accepted view of scientific realism -- the definition I previously gave from Wikipedia. In which case, as Carroll and most others claim, many-worlds is the paradigm 'realist' approach to quantum mechanics the wave function encapsulates what the external world is 'really' like.
