I'm not sure why this question was closed, as it seems like a perfectly valid inquiry on whether or not a certain expression is considered sensitive or offensive in the English language. This seems like quite a valid question, and others like it have been asked. It seems like useful information to know whether or not a term is offensive, and it directly pertains to English, as it is an English expression. Why exactly was this question closed?
It's not a real question. The title gives the impression of a question, but the text simply says "Look what I found. Interesting, eh?". If you had worded the main text to make it clear you were serious about the question and to show some constructive argument, it might still be open.
