So, "atheist extremism" and "aggressive secularism", eh?
Right: tailor-made international charter flights (on time); custom-built bullet-proof Mercedes skyscraper; one-off rock-festival podium and sound system; phalanx of black-suited bodyguards straight out of Reservoir Dogs; costumes that would make Kiss blush; orchestrated cheering weeping street mobs; twenty-four hour uncritical media coverage; oh yes, and £15m+ of public money. (Have I missed anything?)
Looks pretty aggressively extreme to me, at least in marketing terms. Not many atheists get that lot.
