Patriotism
As historian Howard Zinn said, “If you’re Norway, or some other small country that does not represent a military threat, there is no harm in establishing a sense of national pride. That is not true of a military superpower that has the potential to annihilate this planet many times over.”
If being an American “patriot” means striving to improve the quality of life for all our citizens, or making our country a more ethical player in international affairs, that’s fine. If it means cheering for America regardless of how wrong it may be, that’s dangerous.
