It's more like people with religious and political motives like to frame this as if there's genuine debate around the issue rather than mountains of scientific evidence that keeps piling up about the nature of existence and all things residing within it.

I say political because believing in free will is correlated with believing in both extrajudicial and judicial retribution. In other words, people often choose to believe that people made terrible choices in lieu of their actual available choices according to a deterministic universe and that those people deserve to essentially be tortured in utterly inhumane conditions.

I think it's a mistake to even give these free will proponents a platform, same as fascist ideology. Belief in free will seems situated on a moral axis more often than it does a scientific/objective front. Many of these people I feel aren't arguing in good faith, which is ironic given the propensity towards a concurrent religious belief system.
