I think Calvinists enjoy watching many other Christians squirm with their Sovereignty of God syndrome. God choosing to send souls that are equally and hopelessly unqualified as they are to Hell.
Is that really what you think? Why would the thought even occur to someone? Or was it just one more hateful thing to say?
Why do they enjoy this? Total depravity is at work
Oh. You not only think it now it is considered fact. And gets applauded as the voice of reason? Now that sounds like total depravity at work.
Here is another way in which it is at work. Let's take a walk back to the Garden of Eden. Adam has told Eve what God has told him about what they can and cannot do regarding food from the trees. God has provided everything for them. Plenty of delicious food, eternal life, a place to live and thrive with nothing evil at all. One thing He withholds. The knowledge of evil as well as good. The knowledge of which they can only get from that one tree. The judgement for eating of it is death.
Along comes the serpent and suggests to Eve that she will not die, that God only keeps that fruit from them because He doesn't want them to become like Him. She will be much better if she does eat it. Well this sounds good to Eve so she eats it and gives to Adam and he eats to.
Time goes by. Children are born in pain, Adam and Eve often can't get along, they are exhausted with their labors. In time the whole world is filled with sinners all fighting for supremacy and autonomy for God has become their enemy. The central cry against Him can be summed up in "I will do it my way!"
But good news comes, the Redeemer arrives to rescue people from this evil they cannot escape that dwells in them. He dies on the cross to take their penalty for them. Well this infuriates the serpent and he begins to sow seeds here and there in the meeting place with God, among those God has redeemed and is redeeming.
"God has made a puppet of you," he whispers. To another he says, "Jesus may have died for you. Lovely. But look at all the people God didn't save. If He only saves some look how evil that would make Him. He did not save you because He chose to. You could never trust Him to do that." And some take up this cry and ponder how to make God both the Redeemer and at the same time not have to trust Him to redeem them. So a man named Finney takes up his weapons and carries them into the place where they teach this horrendous thing that God would do such an awful thing as to violate the free will that He gave them to do as they please, and set out to kill Calvinism.
For a time it seemed as though he were successful. Generations came and went and there were a people of God who had never heard anything but this new thought that entered into Christ's church, and never gave it so much as a questioning glance. But after many years, Calvinism was discovered to only be sleeping and not dead.
When faced with the possibility of not having autonomy in their salvation any longer, and the horrible fear that if they would have to trust in the goodness of God rather than their own choices and decisions, they began echoing that voice of the serpent. "It makes God evil! God would never, never violate my free will and make me love Him! God wants people who love Him on their own,not people He forces to love Him! I did it my way!"
It sounds good and right to them and they feel much more comfortable believing they made the choice and therein lies their security. Why bother to look and see if those things they think and say about Calvinism are true. It is enough that they can quote pages of scriptures if kept separate from certain others, to deny Calvinism in an endless argument. (Arguing is so fun!!) The added benefit is that it is a good feeling to look down on their brothers and sisters in Christ and say evil things (ah there it is, that dang tree) about what
those people believe, walking the moral high ground, singing, "love, love, love, all we need is love."
I was once a very stubborn reformed calvinist. I speak from lots of decades of experience.
