In the USA, 2 centuries of Supreme Court decisions disagree with you, by people far more familiar with law and it's principles than either of us have.
False.
Fighting words, defamation, threats that convey a serious intent to commit violence, incitement of violence, incitement to suicide, false statements of fact, commercial speech, speech owned by others, counterfeiting, making threats to the President, violations of privacy, state secrets, some forms of obscenity, speech in the capacity of a government official, restrictions on those in the military, inmate speech, and more, are SCOTUS backed restrictions on free speech.
None of the Bill of Rights are absolute. They can and do have exceptions. For example, try building a nuclear weapon and see how far claiming you have a 2nd amendment right gets you.
Please educate me as to these limitations are?
