Could I ask native speakers to help me please? Thank you in advance.
You have a preconceived opinion about non-natives' ability to cope with certain tasks and, unfortunately, these notions all your threads overtly carry. Your bias is a message towards a group of people that I am also a member of. When I offered my help last time, you deleted the whole thread and started it again, probably in the hope of increasing the chances of receiving an answer from a member of that group you favour. Any way I slice the story, you are like a bull in a china shop: grossly tactless. You tramp on people's feelings just to get what you want. In my culture, such conduct does not arouse positive feelings in people. Furthermore, In my opinion, when someone starts to classify people in any way, it brings misery in the long term.
Finally, I am going to present to you my definition for racism.
Racism: the prejudice that members of one race are intrinsically superior to members of other races
race (I do not like this term, race, for humankind): any people united by common history, language, cultural traits, etc
I am not good at English, so I am here to ask for help. And I also am not able enough to tell right answers from wrong answers and so I had to ask only native speakers to help me and I said so in my every post. In my culture, this is a safe way to avoid unnecessary misunderstanding. I didn't know this still caused unhappy feelings among net friends. I'm terribly sorry. I won't use those words any longer.
I am only a keen learner of English and in no way a racist.
