Hey, but the fact that you're influenced by other people's choices doesn't change anything. It certainly doesn't make your decisions less random/deterministic than theirs. To break the joint randomness/deterministic nature of the whole process, you have to posit the existence of free will, like you posit the fact that you're being rational rather than a mere puppet of material processes leading to what you call your mind. As I said above, the whole point of the opening post is incoherent in that, if it's true, then what we're saying is meaningless because we were led to say it by mechanical processes in our brain. Who ensures that those processes lead to truth? A magnificent "truthfulness law" coming from God knows where?
