Let's please look at Romans 9:20, which you all like so much. It actually confirms free will. No one could talk back to God otherwise. In fact in Calvinism, no one talks back to God, they do exactly what he programs them to do.
Lol!!!!!!! Not even close to being true! You simply cannot see what is plainly before your face.
No one is denying sinners can't sin or talk back to God, nor does mans ability to do so mean he has free will to save his soul. Talk about eisegeting Scripture! That's not what that text is discussing at all.
We affirm man is capable of doing this so your latter point is a straw man. No man is free in their will, or otherwise, outside of Christ but is bound in sin; John 8:36f2f.
But to the point and real meaning of Romans 9:20 which characterizes you, the man is complaining against God's purpose to save some, not others, and then crying to God because he can still find fault with man even though he leaves him in such a condition and finally condemns him. He is angry with God and calling him unfair if he does so.
That's you in a nutshell, you call God out, and call him a monster because he can and does do these things. It appears you think God owes every man ever a chance to vote himself into heaven. He owes no man anything and such a notion is not grace whatsoever.
This is why I say it is true that you are in fact hostile in your mind toward God; Colossians 1:21; Romans 8:7-8 &c. You are at this time apparently at enmity with him.
