You weren’t being offensive or rude, you weren’t even telling him that he needed to learn to be fluent in English. You were saying that the interviewer and the news outlet need to be more considerate of the fighters. I agree that they shouldn’t have made him interview in a language that he wasn’t fully comfortable with speaking, it just looks like it’s a big joke rather than a pre-fight interview.
I have never heard you offend anyone. The things you say are never done with malicious intent or hate. Too often these days everyone is offended by something or someone. Keep making people laugh
