Why is gossiping about someone behind their back wrong?
Gossip is an act of cowardice
Gossip strains relationships, ruins organizations and destroys friendships, and the person being talked about is unaware and cannot defend themselves. That makes gossiping an act of cowardice.
The irony is that the person we are gossiping about is unaware and so cannot defend himself or herself. Thus gossiping is an act of cowardice.
