Comments sections are great for the same reason Trump is great: they shine a  light on the squalid little black heart of the self-styled "conservative" movement and display how vapid and morally and intellectually empty its true believers truly are. 

In this thread, observe the common rhetorical conservative "tactic" of 1) making a race-baiting comment; 2) when called out for said race-baiting comment, trying to turn the tables to say "you're really the racist! You brought race into this!" These people who do this are unable to help themselves; they were raised on a steady diet of resentment  and think poking fun at the physical characteristics and ancestry of other people is the height of wit. 

They know they're being left behind by a world that finds them as distasteful and ignorant as the people who threw rocks at little black girls getting off school buses in the 50s.  Unable to adjust, they resent those who did. So they vent here. The dogs bark but the caravans move on.
