Personally, I don't like the whole newspeak thing with X everywhere. But I'm a language teacher, and I grew up in San Diego, where the bordertalk is incredibly mixed. Both these things help me to understand that young people will speak as they please, and my opinion doesn't matter a donkeyfart.
What's going on with Larreta is that this is for consumption. He's pandering to his hardcore right base, because he's scared spitless that Milei will take away that sector of the JxC (does that X count?) vote.
Does it seem to anyone else that Cristina and Maximo and La Campora are being suspiciously quiet of late? There is a Napoleonic maxim, "never interrupt your enemy when he's making a mistake". Just a thought.
