Yes, the word sacrifice is way over used these days. Even worse is the word hero. I sometimes think people who have been deemed heroes outnumber the people who haven’t. Every soldier even if they never left the US, every cop, firefighter, school teacher, social worker, utility worker, community volunteer, etc etc. are designated as heroes now.
Back to the signers of the Declaration of Independence, my wife is related to three of them, George Read of Delaware, and George Ross and James Wilson of Pennsylvania. In each case they are either the sibling of or were married to the siblings of her direct ancestors. American blueblood. No wonder her mother objected to our getting married. LOL
