That's pretty extreme. First, freedom of speech is not freedom from consequence of speech.
And second, freedom of speech only applies to public forums. Why would a private enterprise need to put up with someone spreading vitriol and fake news?

Why am I a "cancel culture SJW" if I kick you out of my mall?
