What were the public reactions on social media following Luigi Mangione's murder of United Healthcare CEO Brian Thompson?

The social media reactions to Luigi Mangione's killing of United Healthcare CEO Brian Thompson were extraordinarily polarizing and unexpected. Rather than universal condemnation, many people expressed jubilation at the murder, with some even calling the Ivy League-educated Mangione a "Robin Hood" figure. The public response included starting GoFundMe pages to raise money for his legal defense and organizing bizarre "assassin lookalike contests." These reactions reflect deep-seated frustration with the American healthcare system and insurance companies, where public anger has reached such levels that violence against a healthcare executive was celebrated rather than condemned by segments of society.
