I'd almost be willing to call it a draw and be done with this argument. You don't have any evidence to actually back up your assertions that everyone ALWAYS has a "choice".
No, it's not a draw in the least. Here's the deal. You and I both agree that there are those who can make choices. This is stipulated. You and others make the argument that for some it is impossible (or they are unable or lack the functionality). That is a positive assertion. I cannot possibly prove that everyone has a choice just as nobody can prove any absolute. I can draw an inference, which is what I've done. I have seen no evidence that for anyone a choice does not exist. It is your job to prove your positive assertion, not mine to prove an inference.
I quoted the Harvard neurologist when he said, "all current mainstream formulations agree that addiction diminishes voluntary behavioral control. At the same time, none of the current views conceives of the addicted person to be devoid of all voluntary control and thus absolved of all responsibility for self-control."
This, this hand-waving that the "science says so" is just a load of malarkey. Science doesn't say that. Like the guy says, none of the current views conceives of the addicted person to be devoid of all voluntary control.
So, prove your assertion. You and others claim that some have choice and some do not. Explain how you make that distinction. Don't push it back on me to prove that every single person in the world has something that we both agree exists in most people. You made the distinction, so prove it. Your assertion needs to be supported whether I've made an assertion or not.
And don't come back at me with this stuff about degrees of control. That's a point on which everyone agrees. Everyone. You guys take it one step further and claim that no control exists. Support it or retract it. Don't cop out by calling it a draw.
