Yes, that is a strong element. ANother, related one, is the compulson to degrade and humiliate and dehumanise.

They do not merely disagree, protest, critique - they want to simultaneously degrade and demonise. So they make out their opponents to be sexual perverts and mentally sub-human or devilishly demonic (the paradox is lost on them since the dehumanisation is the point).

Solzhenitsyn and others documented this extensively when reporting on the Soviet method of psychologcal strategy and tactics, others have written about the fascists ways of psychologically breaking their opponents. Today we notice these tactics among the left and the militant activists of their various pet identity group.

The phrase, 'her majesty's loyal opposotion' doesn't chime with the Left anymore. opposition to them is evil and/or subhuman. their rhetoric cofirms and reinforces that in their own minds in their every utterance. They are not debating democratic equals who are on their level but think and reason differenly, they are fighting evil demons. There is no 'loyal opposition', no recognised, shared foudation when you are battling evil demons.  This requires their constant sexually, mental and moral dirtying, degrading and dehumanising those who oppose them. 

There are honourable exceptions, some sober, rational voices can still be heard on the Left but they are over-shouted, over-snarled by the mob. It has always been like this.
