I don't see the reason for all the hate either. It'd be different if he was racist, or anti-religion, or something like that where he just makes enemies. But in his case he is literally a man in his twenties playing video games. A lot of people are literally angry because he's the most subscribed youtuber out there, and while he sincerely has an unbelievable amount of subscribers, it doesn't make him suck, or a faggot, or anything like that. It just makes him successful to the point of other people hating him for it.
