Uh, there's a matter of degree.
In the US, that'd be protected political speech. The most one could expect is scorn.
The UK may have a lesser speech protection than the US, but still a much broader set of political speech is allowed than in Russia or NK.
The degree gap is usually quick to be bridged, via this common anti-fallacy called "slippery slope". Give it a few more years.
That's kinda a silly argument, given that free speech rights have generally increased in the UK in the last few decades.
Slippery slopes are good to be aware of, and hope to avoid. They aren't inevitable. Things don't progress constantly towards the worst possible state.
