Why are Dems and Libs so racist?

I just have to ask, why do the Democrats and Liberals feel the need to be so hateful and racist all the time? They are the party of slavery, the party that started the Jim Crow Laws, the party that couldn't p the civil rights acts until they got the votes from Republicans, They called both U.S. Supreme Court Justice, Clarence Thomas and General Colin Powell, Uncle Tom's. They called Secretary of State, Dr. Condoleeza Rice, an Aunt Jemima. Recently, they celebrated the legacy of Senator Robert C. Byrd, a former Klu Klux Klan member, and segregationist. And this week they have attacked black conservatives and republicans as traitors to their own race. Why can't they stop all the hate?
