  Local or national politics can trigger potentially dangerous hate in someone.
But with a third of the world's population eligible to vote in elections in
2024 alone, we lack understanding of how individual-level hate multiplies up to
hate behavior at the collective global scale. Here we show, based on the most
recent U.S. election, that offline events are associated with a rapid
adaptation of the global online hate universe that hardens (strengthens) both
its network-of-networks structure and the 'flavors' of hate content that it
collectively produces. Approximately 50 million potential voters in hate
communities are drawn closer to each other and to the broad mainstream of
approximately 2 billion others. It triggers new hate content at scale around
immigration, ethnicity, and antisemitism that aligns with conspiracy theories
about Jewish-led replacement before blending in hate around gender
identity/sexual orientation, and religion. Telegram acts as a key hardening
agent - yet is overlooked by U.S. Congressional hearings and new E.U.
legislation. Because the hate universe has remained robust since 2020,
anti-hate messaging surrounding not only upcoming elections but also other
events like the war in Gaza, should pivot to blending multiple hate 'flavors'
while targeting previously untouched social media structures.
