you have to realize, being subjugated to laughter and mocking by the crowd is part of an athlete/competitor's job, real sports or video game.
if there hadnt been so many silly viewers watching, the tourney organizers wouldnt make any money, and conversely the pros wouldnt get paid nearly as much either, and then there wouldnt even be a competitive scene to begin with.
in what normal world could playing video game gets you paid, if not better paid than a lot of hard, laborious jobs? only a large pool of immature and toxic could this happen, and that goes for actual sports' audience let alone a video game's audience - so you are only being naïve for getting upset over the natural ways of things.
and yes, if i was in kyojin's shoes, i wouldnt give a flying fuck what kids are saying about me since im getting paid 10k+ a month + prize money LOL. its like winning the lottery while getting stunk by flies. its all surface noise so who gives a fuck?
in fact i bet you care more about hate towards kyojin than kyojin himself does. grow the fk up and find something better to be upset about lol
