https://en.wikipedia.org/wiki/Freedom_of_speech
First sentence:
"Freedom of speech is a principle that supports the freedom of an individual or a community to articulate their opinions and ideas without fear of retaliation, censorship, or legal sanction."
Emphasis on principle, not on law.
There are certainly much better XKCD than this one but it isn't wrong when it describes behavior of communities. It isn't wrong when it declares the irrelevance of the first amendment of the US.
But where you are wrong is that you support free speech. You are more focused on the consequences for the people whose uttering you dislike. It is intellectual weakness if you are afraid to face opposition.
