That country doesn't, and never has, existed. All societies, no matter how free they may claim to be, have limits to what they will tolerate, and all will ostracize you for opinions if you move outside that box, be it through public shame or imprisonment.

When the US was founded, one would have been ostracized for being a loyalist to the Crown. Or an atheist. Or, depending on where one lived, believing that blacks shouldn't be slaves, or being a Protestant or Catholic in the wrong neighborhood. And as societies go, the US is incredibly laissez-faire compared to elsewhere, where unpopular opinions have gotten people killed for centuries or millennia.
