I agree about Palestine, where there was a huge, disheartening cry from America in October - December 2023, when the general attitude was that this was all a terrorist attack, and not the beginning of a genocide. I am definitely wary of celebrities who made pro Israel statements then, but I feel many felt expected to, or were just grossly misinformed.
He does sort of just suck though. I feel the internet's perception of his soured so fast in the 2020s, from beloved to loathed, and all he did was keep doing what he always does, just with a tiny amount more selling out, which was enough to snowball the hate.
He wanted the weird image. He implied he was intending to start some sort of harem cult a few years back, which was really a hippie holiday for millionaire women in a very LA way. He absolutely played up his image as a self obsessed creep looking to be worshipped to sell this experience. I honestly feel everything kinda gross about how Jared Leto feels is marketing, although God knows why, as it must hurt his career.
