@ Khandro - I genuinely think you are mistaken.What you describe as "militant atheism" is not a new phenomenon, nor do I feel that it especially militant, unless you class refutation, counter-argument and rebuttal as militant.
There is however and increasing trend for atheists to no longer allow religion and those that preach it an unchallenged free pass - not when their world view impacts upon secular society. Irrational or unevidenced assertions are challenged. Cut and paste preaching is exposed. Illogical points or anti-scientific points are rebutted, robustly.
Above anything else, many atheists, myself included, no longer feel it necessary to offer automatic deference or respect to faith, because in my opinion no religion, no faith is deserving of unqualified respect, no matter how fervently some who post here believe in a particular branch or sect of religion.
Some individuals that argue from a pro- religious point of view are afforded respect based upon the quality of their argument and their rhetoric. Others, who initiate sanctimonious homilies, or cut and paste text; those who offer antiscientific commentary culled from fundamentalist websites; those who refuse to engage in debate with those offering a counterpoint or rebuttal ; those, who when forced into their own original content revert to the arguments of the schoolyard - these people are ridiculed, robustly refuted, made the butt of the joke or the target of sarcasm - and deservedly so.
And whilst several pro religious members of AB have posted to express their admiration or support for one of the more egregious exemplars of cut and paste sermonising, that support has more to do with their sense that they feel their faith is under attack.
Rod Liddells documentary is his attempt to fulfill his own narrative, with highly selective and edited interviews, and a bias to prove his own agenda. Hardly an impartial, objective or balanced view.
