This is a ridiculous blanket question. Some of his stuff, I like. Some of his stuff, I don't like. Most of his stuff is not even what you'd think if you've never read him. He had quite a heart for truth and for people, and was burdened for lost souls in a way Arminians would never acknowledge or undertand.
Have you extensively even read Calvin? Have you read his Institutes to even know first-hand in detail what his true theological emphases were?
I have yet to encounter ANY Arminians who has actually read Calvin's Institutes, and only a handful who've ever bothered to read more than maybe an hour's worth of any of his writings.
The way you portray Calvinism indicates to me that you draw all your understanding from the TULIP model and an inverse approach to the topic by conceptualization.
Have you read Calvin?
Critics of Calvin should read his last will and testament, for it disclosed his heart for others.
He died with very few material possessions and little wealth, but showed good stewardship, and carefully distributed what he had to others to help meet their needs. I was impressed over how humble he lived and how he thought with care for his friends.
I have read his Institutes and reference his commentaries and do not agree with all he wrote, but in the main, he was brilliant and displayed being greatly blessed and gifted by God with spiritual discernment and wisdom.
His will was recorded in a biography of his life written by Theodore Beza entitled "The Life of John Calvin."
