Yes, you claimed this. Where is the evidence that supports this claim?
Why would anyone discuss non-particle behavior when we’re trying to demonstrate particle behavior? (not that I know what you mean by Poincaré's dot or what W-F means.
As far as light being absorbed by one atom, all you have done is deny that it’s relevant, but without any justification. Waves interact over an extended area. “Nuh-uh” isn’t a valid response.
No Google hits for Poincaré's spot, which is a demonstration of wave behavior. Why would anyone use it as evidence of particle behavior? How is this a remotely reasonable expectation?
Yes, Arago’s spot.
Diffraction is wave behavior. Again: so what? You appear to be rebutting a straw man - nobody has claimed that light (or quantum particles in general) always exhibits particle behavior.
(emphasis added) Yes, actually, it does. If particles and wave has identical behavior we wouldn’t make a distinction
The claim being rebutted is that light never acts like a particle. If you observe particle behavior, then it behaves like a particle.
