I agree, but I'm not sure it's being over sensitive. However I am neither a psychologist nor, more importantly, Broman himself, so I cannot speak to his motives and actions.

Threatening to beat people up over insults does sound puerile though. That is high school teenager stuff, or in this case, a grown man making with the false bravado and braggadocio, because it's easy to say you'd do that in some hypothetical situation that isn't likely to happen, because that is assault and battery, and I doubt 'fighting words' doctrine would cover words being said about someone else. Do Twitch streamers have a right to ban whoever they want from their stream for any reason? Sure, it's their stream. But does it make them appear dictatorial, oversensitive, insecure and having an overinflated sense of their own importance to ban people so casually? Yes, and they should not be surprised if people call them out publicly on their behaviour. And I think definitely people who make threats of violence over insults, aren't suitable people to be representing Destiny. I am sure there are plenty of cool Destiny players, even in these very forums, who are better deserving of that kind of access to the game, even if they don't have as many followers. Just because someone is popular doesn't mean they are above criticism, and certainly any questionable words or behavioura by them should be questioned if these Twitch streamers are being chosen by Bungie in an official capacity to advertise the game for them.
