John, in this history of this country, leaders have made all sorts of speeches in different circumstances. Some paid lip service to certain notions, and some genuinely believed it, when there was some type of healing process involved.
I've known many people who defend collectivism by quoting JFK, "ask not what your country can do you for you, but what you can do for your country".
So finding a single quote is not terribly impressive, IMO.
