Being 100% with you, that's the environment I grew up in. That toxicity is what drives certain people, especially in the eastern parts of the world. I can almost be certain that olympic medalists aren't coddled and told ohh nice try after coming up short. They aren't doing it to be dicks, it's as I said tough love to get better. It's all mindset, if you are shaken by banter or toxicity then how will you perform on the stage? When opponents taunt you by actually saying you're shit? As my coach said, "you think they cared you tried your hardest, the only thing they'll remember is the results". If you think the T1 thing is toxic, you have seen nothing yet.
I'll give you another real world example, would you tell to your friends face that theyre fat? My perspective is since I'm a friend and I care about them, I would voice that they're gaining weight and if they need help with that. I just don't believe in sugarcoating things, (same with in game, esports or normal sports, if you played bad, then own it and be better). If the person isn't receptive to it, that's fine then we move on, but I've made my efforts to inform and reach out to them.
