An anti-Israel whackjob academic was Tweeting his little Jew-hating heart out, and he really, really had a case of the Judenhaas Cray Cray.
(You are free to peruse his musings here.)
Well, guess what?
His offer of employment got revoked.
When his venom was spewed all over social media, it cost him his job.
Not because the Jews control the world (if it were only so...).
Because civilized society rejects his attitudes.
No creepy thought-policing necessary. No insidious, tyrannical, "hate-speech" laws necessary.
This shows that individuals always have a choice.
You can think what you want, and always make choices about in which particular fora you wish to share your point of view.
If you want to share your Jew-hating point of view nowadays, it's best probably to keep it to a closed list-serve, or really obscure academic journals that nobody really reads or cares about, and merely exist to perpetuate the phoney-baloney academic establishment.
(Or work for the New York Times, BBC-that sort of thing...)
If you are proudly public about your opinions, you have to absorb the risks and the consequences.
You can also choose to live a gutless, mute, silent life, never offering an opinion about anything and just plod along safely and cautiously until you die.
This, of course, goes for all political opinion from left to right.
In a free society, you are free to write the following:
"At this point, if Netanyahu appeared on TV with a necklace made from
the teeth of Palestinian children, would anybody be surprised? #Gaza."
Or this one: "By eagerly conflating Jewishness and Israel, Zionists are
partly responsible when people say antisemitic shit in response to
Israeli terror." Or this one: "Zionists, take responsibility: if your
dream of an ethnocratic Israel is worth the murder of children, just
fucking own it already."
And in a civilized society, you are also free to enjoy the ramifications.
And that's the way it should be.
