The Online Safety Act and Hate Crime Provision have extended these somewhat into the realms of 1984. But the police do tend to use them sparingly.
This is categorically untrue.
"insulting words or behavior that cause distress to others"
Malicious Communications Act 1988 (Section 1):
"Outlaws sending messages, electronic or otherwise, with the intent to cause distress, or anxiety"
Communications Act 2003, Online Safety Act 2023, hate speech, terrorist legislation all made these many orders of magnitude worse in many ways.
All of the arrests mentioned in this thread in relation to these acts have been campaigns of intimidation, harassment and calls to violence, not simply saying something “insulting or offensive”.
In the UK political expression of free speech is protected by the ECHR, which overrides both those acts (look carefully who wishes to abolish the ECHR).
This is false. But even if it weren’t, it would be unjust. Determinations like “hate speech” are subjective, and have no place in law concerning speech. Without free speech, there is no democracy.
