Hard to argue with someone who doesn't know the difference between emission and absorption spectra. If fusion isn't taking place, then what causes the observed neutrino flux (with improved detectors which have detected the flux predicted by stellar fusion models)?
Gravitational contraction cannot power the observed energy output on time-scales consistent with other observational data. So I ask, what, other than fusion processes, could be the source of the solar energy? Invisible Unicorns running around in giant hamster wheels inside the sun, farting neutrinos in just the right amounts to fool us?
Yup, another Purveyor of Unknowledge has spoken....
May I join the group?
