This is a public forum. People express their opinions and ideas freely and directly. You can agree or disagree, but angry or 骂人is a very bad manner, no matter how many reasons you have.
I never have 三番五次沟通 with you. If you are expecting me to shut up because you said so, then you are making a mistake.
I really think you need to learn how to disuses issues in a peacefully and professional way.
I have to believe that Education in Japan doesn't offer this principle for you to discuss issues in a public place with a very peaceful and professional manner, at least I don' see it from you.
Let's stop until we are ready.
Thanks
