I think it's more of an acknowledgement that there's a price to freedom/liberty and there are fundamental trade-offs involved. I.e. can't have our cake and eat it too.
The difficulty is in finding where exactly the draw the line. For better or worse, currently there are many technically legal yet unsavory views allowed under "freedom of speech".
You've spelled out pretty well the dangers of free speech but if we err to much on the side of caution, that itself causes animosity and discord from (perceived or actual) loss of liberties. And of course, if left unchecked, it can create a culture which embraces more centralized concentration of power, inviting corruption and further concentration.
I'm still wrestling with my own thoughts on where to draw the line and how to balance freedom with safety.
