First a little history lesson. Neville Chamberlain was Prime Minister of England during the late 1930s, immediately preceding Winston Churchill. He and much of Europe watched as Hitler began annexing and conquering middle Europe. Chamberlain earned notoriety for the Munich Accord that he struck with Hitler that basically threw Czechoslovakia under Hitler's bus. Chamberlain thought that by this treachery disguised as "dialog", that there would be "peace in our time". He was absolutely wrong, in spades.
The USCCB has a penchant for not learning from history - or at least not caring about the obvious lessons therein. In the wake of American reporters being beheaded, Christians being crucified, babies beheaded, other minorities being buried alive and driven from their homes to certain death - all at the hands of Muslims - the USCCB wants to engage in Chamberlain-style "dialogue". That is absolutely useless. Are there more "moderate" Muslims? We can answer that question by asking another: have we heard any "moderate" Muslim roundly denounce the barbarism of the more obviously radical Muslims? The answer to the second question is the answer to the first. I have heard of none. Dialogue with these "moderates" is an absolute waste at best. Perhaps the US bishops would do well to read this sermon by St. Bernard of Clairvaux as he called Christendom to arms for the Second Crusade.
Why are the bishops concerned about "dialogue"? Why aren't they proclaiming the Gospel of Jesus Christ, in all its fullness? Perhaps if they focused only on their God-given mission, Christians would not be facing near extinction in many parts of the middle east.
UPDATE - I'm afraid the lunacy is getting worse. See this.
