In other words, Judaism and Christianity as practiced today have no legitimacy, but are merely renegade corruptions of the true religion, Islam.

Contrast this with the current relationship between Christianity and Judaism. While it is true that Christianity consideres itself to be a "further revelation" to Judaism, Christianity does not consider Judaism to be invalid. In fact, the "Jewish Bible" is still contained in the "Christian Bible" and considered foundational.

I'm not going to argue about how well that is practiced, nor about the errors of the past. But the essential position is that G-d did not make a mistake with Judaism that He corrected with Christianity. Judaism was and is a faithful representation of G-d's revelation before Christ.

Shalom.

Essentially, though with the additional requirement that we all reject our misinterpretations and embrace Islam. Or else. Then, depending on our choice, Sunni or Shia, we can fight our fellow Muslims.
