All religion is ripe for mockery and ridicule when it's put out there instead of being kept under wraps by their deluded adherents. Pete's brand is the most ridiculous of all. What you always have to understand about these people is that they always have an "answer" ready. That's how their websites train them. They don't know enough to take on board any counter-argument and will feel only strengthened by our engaging with them. Ridicule is the only answer, I'm afraid. Even then, they don't always recognise that they're being ridiculed.
