Don't you believe God intervenes so man can make a choice? None of the people you are siding with believe that. They believe the gospel is audibly heard and man makes a choice. No intervention from God.
C'mon Cameron how many times must I say it? It's becoming ad nauseum.
God comes to us with grace and truth. Grace is real power to enable that which we cannot do ourselves. We cannot control the sin nature but God can suppress it and does when presenting His truth so the volition of man is free. The choice to accept or reject is there whether you consciously recognise that choice at the time or not. By your own admission, you rejected the Gospel twice before you believed. This is why I say there are only two types of people in the word believers and unbelievers and some of those believers just don't know they are believers yet so they look like unbelievers. That's how you looked the first two times.
If He didn't, we would all remain in darkness, eventually going down into death without escape and when death is thrown into the lake of fire, we all, believer and unbeliever alike, would wonder what the heck was going on because we would all still be utterly ignorant of God and His plan and purpose.
It's not true about the "people I'm siding with" as you put it. We are all on the same side to start with and we all recognise that apart from God's grace all of us are dead, dead, dead and would remain that way. We are saved by grace alone, not our will but that doesn't mean our will does not have a part to play in God's design. Our wills do not cause something to happen (in this case salvation), nor does it cause God to act, granting us salvation. It reveals who and what we are which is why it is important that our response to Christ comes freely from our own soul. God has determined to save believers, when it is revealed we are a believer, God keeps His promise.
Right now, if a wolf in sheep's clothing comes into the fold we don't know just by looking at them, but God knows. He wants everything revealed. He wants both angels and men to see what is in the heart of all so that when He judges, no-one can bring an accusation against Him leaving us, who have limited sight, to be left wondering if it is true or not. Compare the five "I wills" of Lucifer Is.14:13 They were all said "in his heart" where none but God and Lucifer could see. God is revealing the hearts of all men. God does not create wicked hearts, men learn to be wicked by rejecting the good. God is good!
You only need look at all the excuses people make for not believing. God is eliminating them all by doing things they way He is so that in the end, no-one can give excuse for not believing. With Limited Atonement, men have genuine excuses. How can they believe if God is responsible for them not believing. No-one can fight God and win.
