They did not remove free speech.

The problem is the definition of "violence" "incitement" "hate" etc has become SO broad (at the urging of one side who wants the other silenced, coincidentally) that anything can now be classified as one of those things, depending upon the political leanings of those doing the classifying.

The solution? Stop using definitions of things cooked up by academics in grievance studies departments and grifters whose livelihood depends upon finding offense around every corner and therefore have a vested interest in spreading fear thereof.
