It is a standard right wing argument to suggest those dissenting from the opinion of those others with power are very rude to disagree, and must be suffering some sort of affliction for doing so. At the very least, dissent is cast as rude, and as justification for ostracism within society.
Alternatively, the person complaining must be very jealous, and so we get the narrative of the politics of envy.
Move just a little further, and the dissenter is a threat to peace, law and order and must be detained. They become a criminal.
But that is not what dissenters are, of course. They are expressing their human right to free speech, and so to disagree. This right is at the very core of all human liberties. It is the bedrock of democracy too. And that, no doubt, is why fascists and Tories alike loathe that freedom, and seek to constrain it, through legislation and inappropriate police intervention of the type seen yesterday.
Dissent being such a feature of the Elyan potato patch, right?
And behaviour likely to cause a breach of the peace might well be something that should be controlled, no?
