Be generous
In the quote above, John McMurray points out that fear-determined people have no sun in themselves and "go about putting out the sun in other people." Fear makes us narrow-minded and we tend to put down others. Here is how I deal with that: when I notice I'm getting negative, I put a small pebble into one of my pockets. Each time I catch myself using a put-down, I quietly shift the pebble into the other pocket and say to myself kindly, "Well, maybe I can say that differently next time."
