The current political polarization has its roots in three factors. The rise of social media as the primary source of information, the algorithms used by social media platforms, and the unstoppable growth of fake news.

This is the name given to social media and Internet service providers popular with the far right for their greater flexibility in content moderation than conventional platforms.

The prominence that these hate speeches have achieved is worrying because, among other things, it amplifies the visibility and resonance of already existing prejudices and contributes to the deterioration of social coexistence.

Social networks and unscrupulous leaders make for an explosive combination and can be a further factor in the erosion of relations between countries, as shown by the fight over X between Argentine President Javier Milei and his Colombian and Mexican counterparts.

The Argentinean president has not lost the ability to set the agenda and establish deep connections with his electorate and justifies the adjustments to free the country from "the caste". For now, this "war" overcomes pocketbook constraints.

The struggle against anti-Semitism must be a fundamental part of progressive demands, as must be the struggle against Islamophobia, the occupation of the West Bank and the violation of the rights of the Palestinian people.
