According to all valid Catholic theology, nothing in Father Feeney may be taken as a statement against Islam (a reference or two to the crusades meaning we should crusade against Judaism and its false god - that is true, we should do that). Father Feeney opposed the wickedness that is Judaism and that is proper to do. Judaism has nothing to do with Old Testament real faith in the true God. Father Feeney made that point as well.
Father Feeney never advocated violence - and we agree with him utterly and completely on that as well.
