There is a movement on now to tear down the Washington Monument and Jefferson Memorial because Washington and Jefferson were slave owners.
That is fine as long as we are consistent.
The Lincoln Memorial should be the first to go.
Lincoln was an avowed racist and White Supremacist. He opposed the spread of slavery because he feared it would lead to intermarriage and make us a race of “mongrels”. He believed Blacks to be inferior and that Whites should be their masters. He did not believe they should vote or sit on juries.
After the death of Henry Clay, Lincoln became the chief advocate for the Colonization movement. It called for the expatriation of Blacks to some other country. In 1862 he sponsored a bill to fund expelling them to Panama. It failed. The Republican congress wanted Blacks to stay here for votes and cheap labor.
Four days before his death he told Gen. Benjamin Butler that colonization was still his goal and asked him to explore for a suitable country to send them to.
