Over the weekend, Colorado Democratic Congressman Ed Perlmutter slapped his Republican opponent, Ryan Frazier, on the hand while they were debating Obamacare.
When Frazier objected Perlmutter apologized. The debate proceeded.
It is worth noting that Perlmutter is white and Frazier is African-American.
Now imagine if a white Republican Congressman had slapped his black Democratic opponent on the hand during a televised debate. It would be the leading headline in The New York Times and would be played 24/7 on MSNBC. They would speak of the Republican culture of hatred against African-Americans. But because this doesn't fit their view of the world it will be as if it never happened.
