Free will is determined by your past, every action you intend to take it's already in you by your previous experience. And choices that are new to you , you choose by actions of other trough the past. But as a rational and very nonreligious human being, I had my share of choosing wrong, sometimes just for the laugh of it.
Determinism - if you look at it as destiny, something that must happen, or something that already happened and you can't affect that is idiotic. If you look at it in a way you can't change it cause society shapes your decisions every day of your life, you can find a fragment of truth there. But in the end it's your choice, to live among the people to accept people's way, and to do what you learned from your own life experience.
Free will - free will is there, "I think there for I am" is the core of this very own stand or point of view. But now sometimes you can't think, and that's not connected to determinism it's connected to your instincts. We are pre determined in the way in rational or instinct moment we will do anything to survive, but as in everyday life , everyday choices, you have complete 100% impact on everything you do.
Now this is a main example of this debate. I say you do today something, and you choose not to do it, and I say, ah it's already determined that you wouldn't do it. You have an evidence in your head about your will deciding against it, I have poor vocabulary and couple of old mind games to make you think. Religion based itself on this question, and survived 2000 years or more on this stupid question. Cause people don't know how to take responsibility for their lives and their actions.
