Bad diplomacy in recent times has the same roots - a lot of people stopped accepting balanced views. They think that solely their own opinion is correct, and they start calling names (racist, sexist, troll, etc), downvoting whenever someone expresses a different point of view. Being good diplomat requires very mature and balanced behavior, which a lot of modern politicians lack.
