Aside from “love of country”, not even the dictionaries agree on the nature of such love. What is it? A passionate urge to support, serve and defend one’s country? Devotion to the welfare of one’s compatriots? Loving one’s country more than other countries? Being proud? These are not the same things. Plus, they don’t provide much insight into what patriotism means to those who embrace patriotic sentiments without apology. Let’s see what patriotism means to these folks:

America was born—and born of ideas: that all men are created equal, that they have been given by God certain rights that can be taken from them by no man, and that those rights combine to create a thing called freedom. They were free to pursue happiness, free to worship God, free to talk and speak in public of their views, and to choose their leaders. …American patriotism was the repetition, reaffirmation, and celebration of our founding ideas. Peggy Noonan

And here’s what patriotism means to a few of the not-so-patriotic:

Patriotism is the willingness to kill and be killed for trivial reasons. Bertrand Russell  

"It is lamentable, that to be a good patriot one must become the enemy of the rest of mankind." Voltaire  

“The cheapest sort of pride is national pride; for if a man is proud of his own nation, it argues that he has no qualities of his own of which a person can be proud.”  Arthur Schopenhauer  

"The working men have no country" Karl Marx.

“As long as they remain deeply patriotic, America’s poor won’t rise up.” The Guardian 

“Multiculturalism is the opposite of patriotism.” What patriotism means: Guardian Readers  

“Patriotism is a mental association mostly towards a piece of cloth, a catchy tune and the nation's name. It probably was created the first time a tribe needed to expand their territory and - naturally - they had to define the nearby tribes as ‘them’ versus ‘us’.” What patriotism means: Guardian Readers  

The USA is built on war and violence, creating it overseas and a daily dose at home. We have the most people in jail. Guns are rampant. Why would I feel proud to be an American? Not one good reason. So to hell with American and idiot Americans who would even consider a mental midget like Donald Trump for president. What patriotism means: Guardian Readers 

Takeaway: When it comes to what patriotism means to patriotic Americans, those otherwise inclined tend to be condescending, contemptuous, and totally in the dark.
