Back when he was only known for electric cars, space tech and his plans to provide free internet to the whole world with starlink it wasn't as bad if someone not knowing better thought that he intends good.
Then came all that anti union shit and his far right statements and childish behaviour with twitter and a lot of other stuff.
If after all that one still thinks elon means good they are either blind fanboy or really fucking stupid
His trans kid went out of their way to say how shitty he was, once people caught on he just stopped trying to hide how much of a shitty person he is because he can gain a fervent base by saying honestly stupid and immature shit.
