Seven reasons:
1. The CEO is responsible for leading his insurance company through acts of cartoonish evil. Refusing people nausea drugs when on chemotherapy, denying procedures, threatening to stop covering anaesthesia part way through surgery, and for what? They've got a near-monopoly in parts of the USA and make obscene profits through ridiculous mark ups and disgusting practices that destroyed lives - some of the stories of children living without their mother because United obstructed life saving care are truly heartbreaking and never should have happened. Every cent spent on that man's funeral was made on someone else's. And neither the Republicans nor Democrats have any political appetite to address it as they both receive donations, the regulatory agencies have been captured, protests and campaigns are ignored and have no impact. What exactly was left to do? Claiming the CEO wasn't directly responsible and was just another cog in a huge system is the banality of evil. After Luigi did what he did, suddenly health insurance agencies started reversing their disgusting policies and pausing rejections. I cannot condemn him for that.
2. His actions lead to cross-partisan unity that I haven't seen in over a decade.
3. That jawline
4. That smile
5. That body
6. Let's be real, he's almost certainly got a massive dick.
7. I have a theory that although he's straight, I bet he's at least a little bit bi and has fooled around with other guys.
