Response to comments on "Alfvén 'resonance' reconsidered: Exact equations for wave propagation across a cold inhomogeneous plasma"

We agree with both Goedbloed and Lifschitz (whom we will refer to as GL) and Ruderman, Goossens and Zhelyazkov (RGZ) that the apparent violation of quasi-neutrality in Ref. 1 is not a true problem and rescind this particular argument against MHD. However, the rest of the discussion in our paper is independent of this argument regarding quasi-neutrality, and as discussed below, the conclusions in Ref. 1 about the validity of MHD, about compressibility versus incompressibility, and about Alfven resonance remain valid.
