Patriotism is the willingness to kill and be killed for trivial reasons.
Bertrand Russell (1872 - 1970)

"My country, right or wrong," is a thing that no patriot would think of saying except in a desperate case. It is like saying, "My mother, drunk or sober."
G. K. Chesterton (1874 - 1936)

Patriotism is your conviction that this country is superior to all other countries because you were born in it.
George Bernard Shaw (1856 - 1950)

You'll never have a quiet world till you knock the patriotism out of the human race.
George Bernard Shaw (1856 - 1950), "Misalliance"

Patriotism is often an arbitrary veneration of real estate above principles.
George Jean Nathan (1882 - 1958)
