No one ever said Jesus spearheaded a "secular" movement. That would be ridiculous. "Community organizer" is of course a modern term with paticular connotations. But it isn't inconsistent with Jesus's activities as described by the evangelists.

Well, the cosmos is certainly violent and human civilization conflict-ridden. But the gospel is counter-cultural, and Jesus commands love over violence.

Holy non sequitur! Pacifism isn't a specifically "humanist" perspective.
