William Lane Craig continues to desperately defend the indefensible.

...how is he still able to make a living off this?

WLC is popular because he intellectualizes garbage. He takes the terrible theistic arguments and uses flowerly language to give himself a psedo-academic flair, but underneath it's all still garbage. Theists eat it up because to hear their beliefs reinfoced with what they perceive to be as legitmacy is what thry yearn for. As we've seen from the links that theists provide, they are all about reinforcing their own beliefs(I guess we all are in some ways, though), and the more quasi-intellectual the argument, the more they love it.

Plus, they can always use him as an example of a theist that can actually spell.
