"You are a racist/sexist/ xenophobe /homophobe/ abelist " is code for "you are winning this argument, and I hate you for that."The first person in a discussion to call someone Racist, Sexist, Xenophobic, Homophobic or another pejorative term is deemed to have automatically lost the discussion because they have admitted they have no facts or logic to support their position, and thus resort to name-calling to silence further embarrassment.
