Nothing makes us smaller than when we disparage someone else.
Nothing makes us weaker than when we point out the weakness(es) of others.
Nothing makes us more ludicrous than when we make fun of others.
Nothing disgraces us more than when we behave disrespectfully toward others.
Nothing impugns our honor more than when we spread hurtful gossip about others.
Denigration has a built-in boomerang effect. Trying to make others smaller never results in our getting bigger. Trying to make ourselves bigger at the expense of others always makes us smaller.
"Do unto others as you would have them do unto you." - Luke 6:31
Golden. (And so simple.)
