I hate the idea the free will may not exist, I really hate the idea that we may never explore our galaxy much less the universe. O hat how horrible we are to each other over meaningless thing lis difference of beliefs, skin color, sex, sesual prefereance and where we were born.
I'm ok with the idea the a god, God, or gods exist, but it's that there is no objectively verifiable evidence to support that any gods might. The absolute best "evidence" that we have fo a god or gods is the same as we have for hundred of convicted felons that were wrongfully convicted and which is no where nearly enough to establish a scientific theory.
On the other hand, the idea of God (as opposed to a god or gods) is not only dependant on the complete lack of evidence for it, but the blantat changing beliefs about it and what it is/wants over the centuries that do not hold consistent with our evolving morality and values.
