He (Vianney) was an enemy of dancing. You should note that the dances of that time were far different from the immoral and outrageous dances of today. The young ladies were completely covered and had skirts that reached to the floor. If he condemned those dances, what would he say about ours? His condemnation went so far as to deny absolution to those who would not promise to stop going to such dances.. Many persons would go to other churches to receive absolution. Hearing this, he simply commented: If other priests want to send them to Hell, it is up to them.Yikes!
Pretty forceful!
