Error always requires a tolerant spirit in order for it to exist, and even thrive.
We have has many cults and questionable doctrine come out of Arminian Theology ... even today in the "modern" age we have the heresy of open Theism
Calvinism brought forth the "Protestant work ethic," the US Constitution, the Puritans, and the middle class, just to name a few.
If we look at what "tolerance" has contributed to the church we find the erosion of God's Word, ordaining homosexuals, the break down of families.
No thank you, I'll stick with Calvinist view.
