The 'choice' to accept the proposition, or not, is compulsory really. If such a scenario is indeed fact (i.e.) heaven or hell; then whether or not one chooses to accept such a 'gift' is not made by 'free will', but instead by a dichotomous choice alone. --- Like whether or not one chooses to pay their taxes....
So to recap, phase one is to believe such an outline is actually real. But unfortunately, belief is not a choice, in and of itself. It is instead imposed upon one's self, based upon one's interpretation of the evidence presented. But assuming the presented evidence appears justified to such an individual, one may then move on to phase two, accepting/not accepting the proposition, by way of coercion, being compulsory, or even an ultimatum.
Quite frankly, IF such a scenario IS true, any moron is going to 'choose' to 'accept' such a 'gift'. Why, because to NOT choose this dichotomous option would be foolish - like choosing to deliberately not pay your taxes.
So now all one really needs to do, is demonstrate evidence that such a scenario is for real, and not instead made up, and we are in business.
