The slope is incredibly slippery. It starts with Holocaust denial, then pedophilia advocacy, then saying blacks are racially inferior to whites, then to plain old anti-Semitism, then to saying men have higher iq than women, then to militant vegans ("meat is murder you say, incitement!"), then to people wishing that Trump will die in Covid, then to people arguing that U.S. soldiers should be drone-striked.
Two weeks ago Facebook banned a seminar arranged by a U.S. university because one of the speakers was Leila Khaled. A 76-year-old lady who hijacked two planes 50 years ago. How can what she had to say be so "dangerous" that Facebook had to ban her? Sooner or later, this censorship will encroach on what you have to say too.
