“Free Speech” as a civil right granted to all people means you can say whatever you want without the government stopping you or arresting you for the content of your speech.
You are free to say whatever you want.
But it also means that in a public forum everyone else is free to respond to you too.
Yes, you get to express yourself, but everyone else also gets to express exactly how they feel about what you said, to question the premise of your argument and challenge your views.
This is not some vile liberal plot to trick you.
This is how it works.
You might think this point of view is obvious, just common sense, but from the way some folks react to challenge, often taking things very personally, past the point of being offended, it appears that some just don't understand their rights.
Free speech doesn't mean you get to threaten violence when others do not agree with your philosophy or dogma.
It is both a crime and a sin, in as much as it breaks the social contract of our laws and common humanity and it creates separation, thus cutting us off from the divine directive that we should love one another.
It often eliminates any possibility of rational understanding of empirical data, as emotional reactions usually blind and deafen the individual or group so affected.
The benchmark is that you do not have a right to hurt people.
There is no justification for violence except in the case of self-defense in the face of visible physical threat.
If you go looking for a fight you are also on the wrong side of humanity.
If you think you have any right to stop someone from expressing themselves in whatevery way they wish you are already on the wrong side of history.
Nature delights in diversity.
