I loved the Kilpatrick interview and have just bought the Kindle edition of his book..I find nothing to quarrel with except his blaming atheism rather than the ideology of some atheists for the attack on values which both he and I share. But "Christianity, Islam and Cultural Marxism" would be a less elegant title than the one he chose.
In the following extract the significant phrase in the first sentence is not "atheism" but "the left". I personally take common cause with those Christians who understand the enemies of our civilisation. That's why I love Roger Scruton and hate Rowan Williams.
"I use the word 'atheism' in the title as shorthand for both atheists and militant secularists, most of whom tend to be on the left. Many Christians have awakened to the fact that they are in a cultural struggle with secular leftists, but far fewer have come to the realization that they are also in a civilizational struggle with Islam. Fewer, still, are aware that... the left has formed a tacit alliance with radical Islam against the West.".
I suggested, either in this or your earlier thread, Khandro, that the decline of Christianity and its replacement among the elites by dangerous dogmas like moral relativism and multiculturalism have a set of common causes. These are examined in a book I read some while ago - "The Diversity Illusion: What We Got Wrong about Immigration" by Ed West. It's a good read. He attacks among other things popular falsehoods like "We've always been a nation of immigrants" and "Mary Seacole - the.forgotten Florence Nightingale", as well as blowing the whistle on Blair's and Straw's immigration policies.
