[...] Have you ever changed a belief in your life? Did it occur suddenly or gradually over a period of time? Is the assumption that we can persuade other people to change their beliefs realistic or a mere pipedream?
If we change our "programming" at some point in life, it's still (barring brain injury, surgical alteration by outsiders, radical drug effects, etc) the result of our particular identity configuration (at that time) being receptive to whatever external factors bring about that transformation.
Whereas another person -- with different innate and environmentally acquired tendencies slash thought orientations -- may resist change under the same influences (whether they be harsh or comforting). This doesn't mean the resistant individual "can't be reached" at some point in the future, only that he/she may require different triggers or stimulus.
Free will (FW) is not about being able to choose what, who, and where one is at conception and birth. Nor any innate programming, nurturing values, and the socioeconomic situation one acquires as the result of that (without having a choice). Such is erroneously conflating FW with the origins of the subject.
The very notion of the above implies an immaterial and more fundamental version of selfhood that exists prior to being conceived and born as a body, with the latter's capacity to make decisions. Which is incompatible with a natural world to begin with.
Some incompatilists focus on or submit skewered conceptions of FW like that because they motivatedly desire beforehand that FW be contradictory with the human circumstance, prior to the term even leaving the starting gate. And also to wriggle around the possibility of determinism not being strict or absolute, should events not be perfectly predictable -- to still have a hammer to hit FW with, just in case. (Since much ado is also mistakenly made in the incompatibilist camp about indeterminism or randomness being a qualifier for FW.[1])
Free will merely denotes the subject/body being [contingently] free from external coercion (i.e., free to do what an autonomous entity does) and (in legal context, at least) free from clinical conditions (not insane), so that the decisions/acts performed by the subject are indeed the (occasionally excusable) responsibility of the subject:
what the subject wanted (
regardless of consequences, mistaken thinking, ignorance, etc).

[1] FW isn't dependent upon randomness or unpredictability. Totally disorganized interactions cannot output deliberated choices, and intermittent (mitigated) randomness intruding upon and disrupting a regulated system is just another type of external intrusion causing one to do something one otherwise wouldn't. Not unlike a gunman, out of amusement, forcing a non-addict to snort cocaine.
