Or, the paradox might be that the notion of free will IS ITSELF the pre-programmed behavior.
I disagree, probably because I find it too interesting. But I can attest that it is socially expensive. Many people are not quite aware of the extent to which they require certain beliefs to be shared with others, or the sanctions they impose upon those who do not. Even (especially?) when one points it out in simple, methodical, step-by-step fashion why they think the evidence points elsewhere.
If one thinks that disillusioning people about belief if their god gets weirdly testy, that’s nothing compared to challenging - even indirectly - people’s sense of self and identity. Even of self-professed rational people. Some can handle it as an interesting intellectual abstraction, but even most of them break down when organizing their typical daily interactions this way.
