“Every miserable fool who has nothing at all of which he can be proud, adopts as a last resource pride in the nation to which he belongs; he is ready and happy to defend all its faults and follies tooth and nail, thus reimbursing himself for his own inferiority.” ― Arthur Schopenhauer
(And, yes, there is danger of painting with too broad a brush, no matter which nation's nationalism we are criticizing. Not everyone there is a nationalist, for any value of "there".)
