Liberals are clueless and arrogant in a very strange, illogical and suicidal way.
It never occurs to guys like this that their own speech comes across as hateful and slanderous to those at which it is directed. Moreover, their accusations of racism are typically based on their interpretation of so-called “code words,” rather than on any overtly racist content. And when people of their own political persuasion express overtly racist and sexist sentiments against conservative minorities and women, they are silent.
