There's no conspiracy: there's just a bunch of people who may call themselves 'Christians' but who are really liberal secular humanists, who wish everybody else were liberal secular humanists, and so set themselves up to attack Christians who aren't liberal secular humanists in the hopes of blurring the line between Christianity and liberal secular humanism.

It's not surprising that they reject the framing of the debate as Christians vs secularists, as they themselves are secularists. Again, this isn't a conspiracy: they're not working with some secret network of secularists. They just have secularist sensibilities, and so they instinctively take the secularist side against the Christian one.
