>There was no “expiration date” in the constitution.

Article I, Section 9, Clause 1 of the U.S. Constitution (often called the Slave Trade Clause) prevented Congress from prohibiting the importation of slaves prior to January 1, 1808. This effectively allowed the international slave trade to continue until that date, after which Congress could (and did) ban it.

Seems I need to reword my take, as this demands a bit more specificity, but the overall take remains unchanged. Had the 3/5 provision not been made, the South would have further prevented the North from enforcing a ban on slavery and inequality, which was already in place in the North, and in place federally with the "created equal" component in the Declaration, as was argued by founders in court cases.

We can't just ignore court documents and the Constitution itself, along with the Declaration. Not to mention the first draft of the Constitution which had a lot more provisions against slavery before the English forced then to take allies with the South or die. They had no choice but to agree to the South's terms and allow for the South's slaves, temporarily. A stark difference from the previous Constitution of the first Congress.

You can try to frame it however you like, but you can't hide the fact that the founders wrote that slavery is bad, and they don't want it in this country even before it was a country. And they subsequently fought to eliminate it as soon as the wars were over. Those documents remain, right in the face of your argument.

Sundown towns existing doesn't change that. There was no sundown country, just as this isn't a sex cult country, despite there being some law breaking Nexium participants setting up shop and torturing people. It happens, that doesn't mean we as a country yearn to have more racists walking around. In fact, I think if you read why Republicans voted Trump, it's because they perceive immigrants to be racist and they want to reduce the inflow of racist ideology and rape culture into the country. That's exactly the scare tactic that their advertising relies on. They believe they are the ones who aren't racist, just like Democrats.

(I hate both political parties equally by the way. I'm not sure if that's clear from my commentary. But I reject the South's view of history because I can read the damn court cases and see that it's a total fabrication. And I know that Democrats like to spread that version as justification for why black people need help, and I think they know full well that it's bullshit, but it convinces juries on rare occasion so they continue to use it.)
