You may even wonder if you were rude in the debate, if the way you replied to a comrade may have hurt his feelings. I’m usually very careful about this. Whenever I have to criticize a comrade, the first thing I do is try to protect him to keep the criticism from being destructive, so it won’t demoralize him and so, while serving as an example for others, it commits and stimulates him.

–Fidel Castro, Nothing Can Stop The Course of History, December 1986
