So I learned in Sunday school. Something which seemed so straightforward as a kid I see now as being much more slippery and sophisticated. We are forced, daily, to make judgments - to choose right from wrong, to choose this way over that way, to pick what is more helpful from less helpful.
Good judgments keep everything going.
Here's the distinction. You go to a doctor, who listens to your chest and your cough, asks questions about your lifestyle and smoking habit. That is making a judgment. Now, that's being judgmental, and leads to a short career track for a doctor. Judgmentalism is pervasive.
