I can understand why, but at the same time, if he really enjoyed and had a passion for games, he'd instead use the criticism to grow as a creator and a person, instead of letting it drag him out of games.
Though I really don't understand sending death threats, especially to people who create games or whatnot. Unless you admit that it's full of subliminal messages that will turn children into racist, sexist sinners who will act on these feelings and commit crimes while feasting on the flesh of fetus they took from a woman, video games are just something used for entertainment purposes. Good or bad, they're meant to put you in a world other than your own, and not every game does for everyone. I don't think that playing a bad game, or even being an eccentric person who is trying to suck up to your boss or defend things that we don't fully understand is deserving a threat to your life or lively hood.
I think that criticism and hate speech should be classified. Criticism is a good thing, as it points out flaws in a way that isn't meant to destroy the passion of someone, but show things that they may have missed, in an effort to help them grow past their flaws, or alert others to the issues so that they can make decisions on purchases. Hate Speech is an attempt to hurt someone, whether or intentional or unintentionally, in which it has no merit or reason other than to fufill a need inside the one saying it. Not liking something based on opinion, and stating why in a polite manner, criticism; saying you hate something because it's faggy and that anyone who likes it should f- off because they're a bad so and so (trying to calm on the bad language), there's no need for that other to make that person good.
Finally paragraph, making it quick. When I first watched Jim's videos, the first few didn't capture me. It was what I was seeing and reading everywhere, about the same topics and very bland. However, I gave him a chance with the "Weird is not enough," and saw that, whether it was my own, or a large collection of criticism, he found a way to do what he was doing, but overcome the (then) flaw of being a white stone on white sand by making his opinions and topics stand out. Anyone who said that he was just stupid, or whatever they said, had no real reason to make that post and state that opinion, since it served no purpose. I don't get why people who have opinions that serve no purpose share them, as they just create drama, and destroy good things.
