You didn't refute a thing. You refused to answer a straightforward question, because plain truth of the matter is peoples beliefs can and often do change over time as a result life lessons, education, exposure to new circumstances etc, etc. This whole 'you're a racist or you not' life sentence is a such a ridiculous suggestion that no one with a modicum of common sense and some exposure to the broader world would countenance such a thing. It's a not a rhetorical trap, It's a highlighting a massive degree of disconnect between what's being said and reality.
