Nothing a liberal fears more than debate. Totally understandable when your arguments are based on feelings and emotion and not practicality or outcome. Their position is almost entirely "we can't talk about it, because it will make us look bad" ...and if you question anything I say or do, it's because of racism, sexism, xenophobia, et al. Slight modification to the quote, but still apt "To understand who rules over you, figure out who you are unable to question."
