Theodore Roosevelt actually said...

"To speak discourteously, insultingly, does not do them any harm; it may irritate them, and therefore, it may do us some harm."

"It is the mark, or it should be the mark, of a strong, self-respecting nation never wantonly to injure the feelings or to infringe upon the rights of any other people."

"For my own part, I have striven and shall strive to avoid placing any obstacle in the way."

"Human nature will not change."
