I haven't read the posts above because this has been previously discussed ad nauseum. However, the question in relation to Arminian doctrine has been admirably addressed in John L. Girardeau, Calvinism and Evangelical Arminianism, Sprinkle, 1984, p. 196-207. As I recall, Girardeau shows how Arminian answers tend to butcher the doctrines of original sin, the atonement, imputation, and/or justification.
I have Girardeau on my website here.
