Calling for violence & terrorism crosses the line from free speech in most democracies, including the UK.
Those people who were prosecuted will face a jury of their peers who are perfectly entitled to find them not guilty.
Well, according to that line of thought, people in the US only face the consequences of going against national security and are free to sue the government for wrongful termination/slander/whatever.
Now we can agree that there's free speech everywhere.
What a wilfully ridiculous interpretation of my text!
I'll type this slowly for you: In civilised democracies, inciting violence against ANYBODY is illegal and crosses the line from free speech. Any decision to convict for incitement lies with a jury of 12 random citizens.
Assuming you live in the UK, you're basically saying that losing your job because you criticised the government is a very grave matter indeed, but what happened to Palestine Action is all nice and dandy because jurors.
For those who don't know: Palestine Action is a collective of people protesting the genocide in Gaza, they would occupy/blockade factories of Israeli weapons manufacturers and "vandalise" said weapons. They were recently declared a terrorist group and proscribed, with thousands being arrested for showing support (including by wearing t-shirts) since.
You're right, losing your job because you said something against the government and going to prison because you wore a t-shirt protesting an ongoing genocide are not the same thing.
Speech in the UK's never been better.
