It really depends on how you define your terms. I see a lot of people defining "free will" in completely absurd ways. It is not the ability to make any decision at all, you can't exercise your "free will" and choose to flap your arms and fly, that's not a physical possibility. Likewise, I see people thinking about natural determinism at the quantum level, something we don't even have a solid understanding of yet. The reality is, we can make choices freely between possible alternatives. If you come to an intersection, you can choose to go left, you can choose to go right or you can choose to go straight. Nothing constrains you to do any of those things, barring brick walls and the like. That's free will. Given the same choice three times, you can make three different decisions. Whether you will do so or not, that comes down to preference, etc. You are not being stopped from doing so by an external source.
