Did we find another leftist revisionist? Yes we did.
Fact: The Republican Party was founded primarily to oppose slavery, and Republicans eventually abolished slavery. The Democratic Party fought them and tried to maintain and expand slavery. The 13th Amendment, abolishing slavery, passed in 1865 with 100% Republican support but only 23% Democrat support in congress.
Following the epic civil rights struggles of the 1960s, the South began a major demographic shift from Democratic to Republican dominance. Many believe that this shift was motivated by racism. While it is certainly true that many Southern racists abandoned the Democratic Party over its new support for racial equality and integration, the notion that they would flock to the Republican Party -- which was a century ahead of the Democrats on those issues -- makes no sense whatsoever.
Contrary to popular misconception, the parties never "switched" on racism. The Democrats just switched from overt racism to a subversive strategy of getting blacks as dependent as possible on government to secure their votes. At the same time, they began a cynical smear campaign to label anyone who opposes their devious strategy as greedy racists.
Every political party has its racists, but the notion that Republicans are more racist than Democrats or any other party is based on nothing more than a constant drumbeat of unsubstantiated innuendo and assertions by Leftists, constantly echoed by the liberal media. It is a classic example of a Big Lie that becomes "true" simply by virtue of being repeated so many times.
