In the United States, freedom of speech and expression is strongly protected from government restrictions by the First Amendment to the U.S. Constitution, many state constitutions, and state and federal laws. Freedom of speech, also called free speech, means the free and public expression of opinions without censorship, interference and restraint by the government.
As long as the government isn't arresting you for your opinions then nothing going on here has to do with "free speech". Individuals and corporations silencing you online is not a "disgrace to the principle of free speech".
