God has mercy on whom He will have mercy, compassion on whom He will have compassion. God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction, in order to make known the riches of his glory for vessels of mercy, which he has prepared beforehand for glory ~ even us whom He has called, not from the Jews only but also from the Gentiles.
He predestines only those whom He calls (and ultimately, without fail, glorifies them). The others he gives up to their own selfish desires, and they get exactly what they choose for themselves.
You can call it what you want. It is what it is. The issue that you have is really with Paul, and ultimately God, not with John Calvin or anyone who understands Scripture as he did. Answer back to Paul, as Paul suggested in Romans 9:19, and to God, as Paul suggested in Romans 9:20, and see where that gets you.
Grace and peace to you.
