So let's take a look at
YOUR (Libby's) beliefs below which has the exact same issue that you raised with your objection of Calvinism
1. We have all been given commandments to follow
2. We all have a choice to either follow the commandments or to disobey them
3. We are responsible for out choices and will be held responsible.
4. We are incapable of keeping ALL of the commandments
5. The basis for sending anyone to Hell is breaking the commandments
6. Therefore man is not responsible because he really didn't have a choice to keep ALL of the commandments because he is incapable to do so therefore God is responsible.
