The ideological direction is important.
When a message is chosen to be conveyed in the main communication contexts – through assertion, repetition, contagion – it becomes a moral dogma.
If for years, in contexts of theoretical intellectual freedom such as universities and newspapers, only one direction has been established, the results in real politics will not be long in coming.
Polarized societies are a human invention; we created them.
When we implicitly adopt the diktat “fascist is the enemy” (as happens in Italy and has happened in France with Bardella) and consider Donald Trump equivalent to Adolf Hitler, what prevents turning an attack into a liberation struggle, normalizing it?

This is one of the most obvious and primary strategies of political communication: strip the opponent of any empathy, dehumanize them, and then attack them.
Democracies are at risk of a truly toxic internal disease: where there is not a single party, everything possible is done to ensure a single way of thinking.
