I’ve often thought many Americans either do not know or do not care to take seriously what our Constitutional Freedom of Speech is. Lest we forget:

“The Founding Fathers' intent when claiming freedom of speech, as enshrined in the First Amendment, was primarily to ensure the free exchange of ideas, particularly regarding political and religious matters, essential for a self-governing republic. They believed it vital for discovering truth through open discussion and testing of opinions.

However, the modern concept of free speech differs in important ways from the Founders' intent. The First Amendment did not initially encompass a broad protection of speech in all its forms, and there were, and still are, limitations to freedom of speech.
Regarding profanity and vulgarity:

In the era of the Founding Fathers, certain forms of speech considered harmful to society, such as blasphemy and profane swearing, were subject to government regulation.

This suggests that the Founders did not intend to protect all forms of speech, especially those deemed morally corrupting or disruptive.

Regarding lying:
Dishonest advertisements and intentional lies about individuals (libel and slander) were not protected by the First Amendment and could lead to legal action.

However, the Founders allowed for broad protection of speech critical of government, even if the statements were false.
In summary:

The main intent was to protect speech essential for a functioning democracy, allowing criticism of the government and the free exchange of ideas. The Founders also recognized the need for limitations to protect the public good. The understanding of free speech has evolved beyond the original intent, but certain restrictions, particularly regarding harmful speech and defamation, were present

There are mere opinions and there are informed opinions, which are usually buoyed by ideas. Once again AI is informative:

“An opinion is a personal view or judgment, often subjective and not necessarily based on facts. An idea, on the other hand, is a concept or thought, sometimes a creative solution, that can be substantiated with evidence, logic, or observation. Ideas are more open to testing.”

Are mere opinions a waste of time?
