I have always thought that the exstence of Free WIll is dependent on whether or not the person belives in Fate, Destiny, or Serendipity.
If you believe in any of these (as I do) then the concept of free will can somtimes be a slippery one,
given that the Powers that Be have already traced a Destiny for you, then every choice you make
has already been made for you.
If you dod not believe in any of the thress, then free will exists in an easier pocket, given that you make your own destiny
then every choice you make is in fact yours, and not guided by the hand of the POwers that Be to get you from point A
to Point B.
The third school of thought finds the balance between the two that states that we were given Free Will and allowed to choose
our own paths through life. Theres a destination, but there is no set path that will take us there. We will never miss the ultimate mark, but we
wont always do exactly what the Powers that Be thought we might do.
Therefore the existence of Free Will lies exclusively with the individual (or group).
The "choice" to be gay is not one that was ever presented to me, I simply was, am and will be.
