“It’s a free country!”

“It’s a free country!” means that the speaker believes that he or she can disagree with another and do something that another disapproves of. The saying has a long history in the United States, although some believe that it’s been used less after the terror attacks of September 11, 2001 and the restrictions of some freedoms to prevent terrorism.
 
“This is a free country” has been cited in print since at least 1819. James Fenimore Cooper’s novel The Pioneers (1823) contained the saying as “it’s a free country, and no one can stop me.”
 
“Free country? Name one thing you can do that isn’t taxed, regulated or illegal” is a related saying.

The Phrase
We’ve all heard the phrase before, at least most of us who are over the age of 25. In fact, those of us over the age of 25 used to hear it all the time. I can personally vouch for that. What phrase am I talking about?
 
One that I used to hear frequently and randomly dropped as a remark or comeback in a conversation: “It’s a Free Country!”
(...)
Ever notice that you seldom hear it now? I’ve noticed.
