For what it's worth, I think your communication hasn't been very clear.
I think 1) you may be assuming what free will means to a compatibilist which it doesn't mean.
2) I think sometimes you are saying they don't believe that what they believe goes against determinism, but you think it does. So some answers were referring to what compatabilists think and then others what their belief actually entails. so, it seemed like you were shifting positions, when you weren't. Though I do think it could have been clearer. I was as confused as FJ when I read the first 10-12 posts of the exchange.
And now I see your lastest post above and I think this supports my sense of where the confusion is coming from. I think that post is now heading in a better direction.
