I agree with very little of this article. But the most egregious part seems to me Mr. Winters' inability to cite much "perpetration of evil" by the US in the 21st-century, as opposed to Hiroshima and central America, the latter of which took place 30+ years ago (and it was that deplorable integrist  retrograde Fulton Sheen who, among Catholic bishops to my knowledge, stood alone in condemning Hiroshima). The most current wars, Iraq and Afghanistan, were supported by Rs *and* Ds. 
Tsk, whatever happened to American liberal Catholicism's  primary sacraments – diversity, tolerance, dialogue? I guess only  for the approved viewpoints.
