Sorry there is no such unicorn called “True Freedom of Speech”. Freedom of speach is not actually free. The constitution grants it to every citizen, but its paid for by the military. Sometimes the price is high, where the service member gives his life to defend your rights.
Now having said that, freedom of speech comes with consequences at all times. One can not yell fire in a theater, the consequence is you get arrested. One can not cuss out ones boss, the consequences is you get fired.
For every action there is a reaction. For example, lets say you are attempting to burn the American flag in public. You have that right, and its covered under freedom of speech. I as a veteran take offense, i scream and cuss you out, and then clock you to rescue the flag. Your consequences is getting clocked, mine could be to get arrested for assault and theft of private property. We both exercised our freedoms, but neither escapes the consequences.
Another example would be to talk openly about killing an elected official, that would get you arrested.
