Nobody names a classification scale after themselves. The scientific equivalent of slapping your name on the Kennedy Center.
How about a scale for hijacking a truly interesting scientific story for misleading, self aggrandizing ends?
Call it ”Likelihood Of Ego Boost”. The real “LOEB Scale”

Musk, Thiel, Trump, Russia, and China share the same goal: to divide, weaken, and destroy the EU, ensuring it never becomes a strong geopolitical player
Elon Musk and his fascist friends in the administration never complain about censorship in countries that actually censor Americans.
They comply with regulations in Saudi Arabia, Russia, and China.
They complain about Europe only because they hate liberal democracies

De todo lo que está pasando en EEUU una las cosas que me parecen más viles es el secuestro, internamiento y deportación de hispanos por parte de la gestapo trumpista. Lo de Gaza es infinitamente peor pero, ¿no merece mayor atención y rechazo por parte del mundo hispano?
This is some intense and vital reporting from the New York Times, showing in detail what is happening to some people caught up in the deportation actions in our country.

De-ICE these flights! Tell ICE Air contractors to halt inhumane ICE Air transports.
Our neighbors are being detained, shackled, then flown out of the country in inhumane conditions—subjected to abuse, sometimes with no emergency plans, no A/C, and broken toilets. De-ICE these flights...
