Ok, let me try to spell this out, just so it can't be said I'm being unfair (I am a teacher after and educating is thus my calling).
We don't know Izaw personally. In person, it is possible that he's a saint; humble, charitable, good sport, etc. Heck, I'm sure he's a great guy face to face. You know him like that so you like him and will obviously defend him. He's your friend (or at least you want him to like you) so it makes sense you'd jump to defend him.
We don't know him in person, we just know the persona he puts forth online. This persona, while once cool, has become obnoxious. He's full of self importance and borders on arrogant (I'm being gentle). These boards have a history with him. Go to the brawl Link Boards, scavenge around the old threads from 08 and you'll find the same hero worship towards Izaw from us. That changed, and it's not because we changed, but because he did. He started doing this, self promoting his matches as the best, his opponents as the best, and he stopped taking criticism. That's called arrogance and ego. When called out he would do ad hominem attacks instead of proving he was right. This became bad for the Link. Meta and scene because he promoted flashy, useless gameplay instead of good solid Fundamentals.
Now, he could have changed, and he certainly has skill, that's not being questioned. But we, because of history, have very little tolerance for his shenanigans and his Izawmbies.
Now, in case you didn't understand something I said, whether due to language barriers or mental ones, please read it again carefully until you understand. If that doest happen, raise your hand and I'll come to your side again and explain it again but more carefully.
Thanks.
