I think you are missing the point.

It is argued that the bishops and pope did not do enough to speak out against the Holocaust.  Whether that is true or false is debatable.  For the sake of argument I will accept that premise.

There WERE bishops who DID speak out however.

Whatever the case may be, my point, which you did not address, was that the same logic you applied to abortion could have been applied with equal veracity to the Holocaust.
