You cannot simply evaluate a person by his棋力, but actually as we seen, you often did so For example,. You talked on the level difference between Cabbage and GM Ng, you said Master Kng is a lower Grade A player, you said Ji Du never got Top 8 in Grade A, and you named another player as 9-lose what, etc. Yes, all these you have mentioned before are ture, but It was not polite or respectful to be saying so. When you were talking about their weakness in 棋力, and ignoring their contribution to chess, how would you wish to win others’ respect?
The more you talk on one thing, shows the more you care about the thing or the more you are accomplished in the thing. So is it because you care about 棋力 more than contribution, or you are accomplished in 棋力 but short of contribution? When you were not showing enough respect to their contribution or not enough 修养 to their 棋力, how would you wish to be treated with respect and 修养 by them?己所不欲勿施于人。
Personally I don’t think One Knife’s words were towards your Mum, you may think by another way, if you treat everyone like your Mum, be polite and respectful, you will win a wide measure of toleration. The way how you are, determines the way how you think. Think about, why One Knife is polite to the rest of 棋友, but you think he's not polite to you? Is it because you are different from the others?
Last but not least, I believe you are still welcomed by all the 棋友 here, as 火影, but not as bls. I believe you still can receive the greetings from One Knife, like everyone first time joining 悟入棋途 (except me, still haven’t received my peach…)
