It’s over the top and stupid because he’s using crowd psychology, it’s language tailored to elicit an emotional response based on irrational fear and anger. The “truth” is delegated from above, it’s true because the “authority” says it’s true. The intent of this type of rhetoric is to mobilize supporters to commit violence.

Since fascism’s mythic power is automatically sapped by the renewed ascendancy of the private over the public sphere of life which ensues once political stability and relative social harmony are restored, it can only maintain its momentum and cohesion by continually precipitating events which seemed to fulfil the promise of permanent revolution, of continuing palingenesis.

Though it may seek through agitation and propaganda to develop into an ‘irresistible’ mass movement, fascism must always in the last analysis be imposed by an elite in the name of a national community yet to be realized, and whose realization, even once the movement is installed in power, will initially (and in practice indefinitely) involve reeducation, propaganda and social control on a massive scale.

Since only a minority of the population can be temperamentally susceptible to converting spontaneously to fascism or becoming the new breed of homo fascistus, and since even at the height of its popularity, no modern regime can enjoy total support, the thorough-going ideological coordination of the national community could never come about ‘naturally’. A grotesque parody of it has to be enacted through the extensive use of propaganda and terror.

Nature of Fascism, R Griffin.

The means of action of the leaders. Affirmation, repetition, contagion

When, however, it is proposed to imbue the mind of a crowd with ideas and beliefs—with modern social theories, for instance—the leaders have recourse to different expedients. The principal of them are three in number and clearly defined — affirmation, repetition, and contagion. Their action is somewhat slow, but its effects, once produced, are very lasting.

Affirmation pure and simple, kept free of all reasoning and all proof, is one of the surest means of making an idea enter the mind of crowds.

Affirmation, however, has no real influence unless it be constantly repeated, and so far as possible in the same terms.

When an affirmation has been sufficiently repeated and there is unanimity in this repetition … what is called a current of opinion is formed and the powerful mechanism of contagion intervenes. Ideas, sentiments, emotions, and beliefs possess in crowds a contagious power as intense as that of microbes.

The Crowd, Gustave Le Bon

“Influencer” is just the propaganda term for propagandist.

Republican rhetoric follows Le Bon’s The Crowd method: Affirmation, Repetition and Contagion.

First they espouse an idea or belief (ex. Radical Left are violent animals). The crowd accepts these statements as true, regardless of reality.

Then blast it on repeat through every medium so it becomes internalized in their minds.

Finally, the contagion phase, where the crowd is spurned to action, whether it is getting out to vote, storming the capital or going door to door murdering “The Enemy Within.”

It’s not difficult to see what the fascist intent is behind the extreme violent rhetoric.
