Also the problem is the misunderstanding or over extending the freedom.
"Freedom of speech" does not equal or extend to "Freedom from consequence". In letter and spirit, its liberating to have "Absolute freedom of speech" but, just because we can do something does not mean it needs to be done. Usually people who think about consequences understand the repercussions of saying something, wont usually abuse this power. Its people who dont really know how to draw the line.
Having said that, drawing that line is not so easy all the time. Just like how everyone does something stupid sometime, and everyone is bad at some things while genius at another, etc, etc. So no one is a absolute stupid, and no one is absolute genius. Similarly people could cross the line from being passionate to being abusive. From being supportive to on we while becoming toxic to the other side.
This is a kind of mental health nuance that as a species we need to learn to navigate and may be empathy could help, may be something more is required. End of the day social media is just a medium that creates facilitates. Using the absolute benefits and navigating the edges of "Freedom to speak freely" is a human skill to master.
