If your way of talking to kids gets you fired, it was atrocious in the first place. "It takes a village to raise a child." is not about carte blanche to abuse any kid that you encounter.

The saying is about kids watching and learning from their environment - from how adults act. If you set up to be jerk or take advantage of random kids that happen to be around, you are teaching them to take advantage of people. And no amount of yelling "their parents are responsible because they did not stopped me" is going to change that.
