Look up where the word comes from. It comes from Greek mythology.
In mythology and legend, a man, often of divine ancestry, who is endowed with great courage and strength, celebrated for his bold exploits, and favored by the gods. A person noted for feats of courage or nobility of purpose, especially one who has risked or sacrificed his or her life: soldiers and nurses who were heroes in an unpopular war. A person noted for special achievement in a particular field: the heroes of medicine. The principal male character in a novel, poem, or dramatic presentation.
I think most American's are heroes if they: pay taxes, participate in our democratic republic, defend liberty when given the opportunity.
Some wear uniforms, and we honor them on Armed Forces Day.
Others wore uniforms, and we honor them on Veteran's Day.
Some died wearing uniforms, and that's what Memorial Day is for.
I like to think the broadest definition of heroes are celebrated on the Fourth of July.
my friend...those who know me...recognise the irony in my words. Of course you are correct.
