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.
