An excellent example of the traditional schema for rejecting the Immaculate Conception can be found in the book The Orthodox Veneration of Mary the Birthgiver of God, by St. John Maximovitch, the relevant chapter of which can be found here.

If one aspect of original sin is inheritable corruption of the body, why should the Blessed Mother not be preserved from it? After all, she contributes 1/2 the matter at conception; if God were to purify the matter miraculously, one could make the case that the Blessed Mother is not really a mother at all, just a womb or incubator.
