"Yes we are creatures with a free will. Just read GOD'S word, and you will see that in Genesis it is recorded very plainly that we have the determination to do as we will."
Firstly, in an intelligent discussion as this you have to use your own discretion and not follow the words of a book.
Secondly, you can choose something even if you are not free to do so. For instance, if you are tied to a chair, you may choose to not be in the chair, even though you can't necessarily get up. That goes into action, we're just concerned with choice. Two different things.
In regards to the chocolate shake, you can choose not to want it and still want it at the same time (carnally speaking). In THIS case though, you have to beleive that you are not in fact what you are presented as (what clothes you wear, how much you want a chocolate shake, the languages you speak) but how you are related to those things, that is how you CHOOSE them. This is a rather strange concept since it would imply that YOU in fact do not want a milk shake and then you have to ask: who wants it then?
Also look at it this way, even when you are proppelled forward by society or whatnot, you're choosing to do so. If you are standing at the edge of a cliff, you have the choice to jump off or not. If you are then pushed after choosing not to? So be it, your choice was still not to jump and thus your freedom of will is not impinged upon, only your ability to act.
How am i doing, making any sense?
