I don't understand these people that hate her so much, even if you disagree with her. All she has done is create a series of videos pointing out what she thinks is wrong with the gaming industry and she gets death threats. Why is no one allowed to be critical of video games? If anything, they are just proving her point by responding with violence.
Perhaps the reason for your confusion is because there has never actually been a response with violence against her?
"the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation..."
Death threats would certainly qualify under that.
