Drama is inherent to competitive gaming
You do not know FrosT. You do not know Patmen. You do not know a single player on Global Esports, or PRX, or FNC or any other team.
You will never know any of these people and that's how this is supposed to go.
Anyone's allowed to hate on teams, players or coaches for any reason. In fact you don't even need a reason. Sometimes you just dislike someone's vibes and that's fine. You don't have to rationally justify your hatred of a person you'll never know (As long as you're not going and personally harassing them on twitter or some shit). This shit ain't that serious.
Drama and online criticism are inherent to e-sports. The answer is to hate on the teams/coaches/players you dislike while keeping it within reason and not harassing anyone personally.
As a long-time hatewatcher of many a team, I promise you this is very doable.
Reject parasocial behavior and start hating for the love of the game.
