Did you?
I am aware of the 1619 project, a laughable contention that America wasn't founded in 1776... but 1619 when the first 20 slaves set foot on out shores.
I don't know what's in the book but I'm sure it's just an award for attacking white men... But what the 1619 project may not realize, or if they do they deny it, is that The United States didn't create slavery and wasn't built on slavery; it ended slavery - until the left found a new, modern, form of it with illegal immigrants.... but I digress.
The slave countries were the UK, Spain, Portugal, Germany, Italy, Canada, and many African nations, among others. The United States led the way in ending slavery.
The United States Constitution included the beginning of the end of slavery right from the beginning:
United States Constitution - Article 1 Section 9 Clause 1 said:
The Migration or Importation of such Persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the Year one thousand eight hundred and eight, but a Tax or duty may be imposed on such Importation, not exceeding ten dollars for each Person.
What did that Founding Father, you know: the one whose statues the left wants removed, make sure was passed and signed in 1808, Thomas Jefferson, on the very first year the Constitution allowed for it? He signed the
Act Prohibiting Importation of Slaves. In less than 60 years, the United States would be in a terrible war with the death of 360,000 Union soldiers fighting and killing 265,000 of their Confederate brothers to keep the Democrats in the South from seceding so they could maintain their legalized slavery in perpetuity.
