Any frank Calvinist must admit that, it appears to be as simple as that. If this is what people understand it to be, and he wants to say that they have not understood the doctrine, then the Calvinist must acknowledge that it's not for lack of understanding of the English language that they have come to their conclusion.
Besides this, notwithstanding the bluntness of its statements, the Westminster Confession of Faith uses notoriously peculiar language on these points in Chapter III.
Now, we revisit the question of why Calvinists object when opponents repeat what Calvinists confess. The answer appears to be, because it evokes hatred of God in those who do not know God, if this be God. This appears from section 8 of chapter III:
This gospel of Christ, according to Calvinists, is to be preached freely to all men, and they are to be urged with all sincerity to trust in it. The gospel should never be replaced with teachings on election and predestination, which cannot have any profitable meaning except to those who have trusted in the gospel. It is never to be said, "to be saved, you must be elect", because, what can men do to be elect? Therefore, if Calvinists find that their doctrine concerning salvation is being described by others as "you must be elect", they will object (or at least, that appears to be what their confessional documents tell them they should do).
It is never to be said, "judgment is based on God's decree", or "most men are damned before they are even born". That is a false way of speaking to the world. Judgment is based on the good and the evil that men do, Calvinists say, because that is what the gospel says. "Turn away from sin, trust in God and believe in Christ" is the gospel, according to Calvinists; "You must be elect" is an antigospel because it subjects men to false notions of futility, and it is therefore an obstacle to faith, something that should not be said because even if the words are right, the spirit of the words as expressed in unbelief is completely antithetical to their believing intent.
And so, what is the doctrine of predestination? The Calvinists say that it is instruction for those who believe, not to credit their believing to themselves, but to God who has had mercy and granted them faith, in love. It teaches those who have begun to trust God, to continue to trust even to the end of the world, because He has been faithful from the foundations of the world. And, those who have begun to obey, learn that salvation is not an achievement to be earned by them: rather, it is God, who is at work in them to make them willing, and able to live for Him. It teaches them when they preach the gospel to others, not to burden themselves with responsibility for whether they are believed: this is a matter between the others, and God. Therefore, if the world is too stubborn to listen, plead with God to grant them ears to hear, in whose hands are the fates of all men. And, because of this doctrine, no one can say "this people or that people cannot receive the gospel, because circumstances have made it impossible": God is the maker of all circumstance. Therefore, plead with God that he would be willing to overcome every obstacle. And if God by decree has the reins of the hearts and the will of men, then plead with God that men would be turned toward life. Predestination is the doctrine of Calvinism, only if it teaches joy and patience, and the assurance of God's faithfulness.
In other words, it is a doctrine intended to instruct Christians in the obedience of faith, not in the metaphysics of "will" in the abstract. It teaches them to credit nothing in creation for their salvation, but only God alone. And they are cautioned never to use this doctrine wrongly: because if these things are preached to those who do not believe the gospel, they will be provoked to blaspheme God. Because if election is preached, they will only hear a perverse message of damnation, or a message which makes them complacent in their sin. But if repentance and forgiveness through faith in Christ are preached, who knows but that God has written their names for the gift of repentance, in the book of life? So say the Calvinists.
