This is a real shame. I've quite enjoyed Bakhtanians' commentary during tournaments for a while now, but he is quite wrong on this.
People certainly have a right to say whatever they like, but tournaments and eSports also have the right to enforce their own standards of conduct within a tournament environment. And language like this is simply unacceptable. High-level fight gaming does not need to be held back by things like this; instead, people should perhaps start acting like adults and take responsibility for their actions. Trash talking is one thing, but harassing someone and alienating people from feeling welcome in the fight scene isn't right. And if fight gaming plans on continuing its eSports rise, standards for how people act in tournaments must be encouraged and enforced for the betterment of the sport and the fighting game community at large.
