I see some people make mistakes in conversation then they counter-attack you if you point out their mistakes. Let's take an example:
Jay: I don't like Chinese food because I hate china.
Xu(Chinese Guy): How can you say these things about Chinese.
Jay(Careful manner): I was talking about specific people. You are my brother how can you even think it was against you, I am ashamed.
So Jay did the mistake and he is trying to defend by diverting the topic. Do we have any specific word or slang for such type of act or behavior of Jay?
