Hello, today at a Czech class (in tertiary / 8th grade), we presented homework on the topic of a classmate's description. My classmate incorporated a racist "pseudo-joke" into one characteristic. I waited until her speech was over and then, as usual, I signed up to evaluate the work. I just said sarcastically, "As the classic says paradoxically, racism unites nations." After several swear words and other honors (such as Moralist ...), "Mr. Teacher" told me that I was stereotypical. I told him something in the sense that something simply has to be insisted on and that there is a difference between stereotype and good manners, and that there are limits that should not be exceeded even at school. He replied something in the sense that at school everyone could say what they wanted (I think he used the phrase "what's on your mind in the language), of course his attitude to the topic was obvious ... he was of the same opinion as my classmate (probably due to the "so-called immigration crisis", which hit us hard as the Czech Republic ... according to my information there are 12 of them "..." when I told him at the end of the class that his approach was not right, I finished 5 for working in class and a note in the wording "In an inappropriate way disturbs the class, please make an appointment." Then I told him I would not leave his behavior unanswered. And that's why I turn to you, because I've never dealt with anything like that. I thought I would write him an e-mail / letter first, because we have problems with a specific teacher first. Then I would write a management mail / letter ... and then maybe it would work out. So please write me how I should proceed. I apologize for the spelling and thank you in advance.
