If you can’t say what you believe is true without going to jail, then free speech is dead. It doesn’t matter if it’s perceived as left or right wing.
The UK rule about speech that tends to incite hatred is what allows them to throw free speech out the window, because “tends to” is vague and covers speech which is objectively true. If I say Jeffrey Dahmer was a cannibal it incites hatred, oops now I’m a criminal.
