"Let's conquer divide-and-conquer by all dividing together, away from it"
Langusges die out when nobody new gets persuaded to use them any more, and language games survive similarly; short of genocide, these things take time to halt (but then die out en masse in larger-scale crisis times).
The news-speak in the present tense hasn't happened yet. Alarmist, even if it does come true. There are some of us who say, "The *#%! needs to hit the fan anyways before things will change." I used to think hate is bad for business. But hatemongers perpetuate the status quo. This is the unexpected consequence of a 50/50 biased political stag-nation.
I see no cure from "individuals". But our "humanity" is a double-edged sword: with loyalty and community on one side, and xenophobia, racism, bigotry, and ultimately aggression on the other. Seems we cannot win in this game. Hatemongers win - in the short term.
