What is impossible in your scenario is for me to have any personal control of past events, which would completely remove any personal input to what I post. Your flawed scenario makes it a logical impossibility for me to personally compose anything.
Oh FFS Alan, how many more times do you need this nonsense corrected, before you actually address the answers, rather than mindlessly repeating the same things over and over again?
You are just assuming your conclusion, namely that there is a "you" that is separate from cause and effect and would therefore have no control. The only logically self-consistent view is that you are part of cause and effect. The "you" that is exercising control is doing so for reasons. Those reasons being the person you have become due to your nature, nurture, and experience and the circumstances you are faced with. If there were to be any other ingredient to a choice it would have to be nothing to do with you or the choice, so it cannot possibly add to
your control or freedom; it would be for no reason, just random.
If you think there is something wrong with that reasoning, why not say what? And try to avoid you past mistakes, like trying to arbitrarily redefine the word "control", or an appeal to consequences, or personal incredulity, or baseless assertion.
