Ah, yes, Master Chief: the hero of humanity who I can't ever recall even raising his voice, let alone cursing someone out; a loyal soldier who does whatever is asked of him to save others, be they male or female. Master Chief is such a poor role model for young boys because he doesn't sit down and have a good cry with his local LGBT sensitivity coach after every firefight, but instead soldiers on as a one-man army to save the world from alien invaders. What a cad.
Stoicism = dead beat dad? I guess? Have these people ever played a game before? Like, any game? If kids actually did emulate characters like Master Chief, the only comms traffic during Halo online matches would be mission specific and to the point. It's because parents refuse to teach their twelve year old sons how to interact with people or discipline them when they act like ignorant fools, that online gaming is largely a flamewar free-for-all. Don't blame Master Chief for people acting like assholes. Most people ARE assholes. Doubly so when there is no chance of an actual social or physical response from their target.
