"NoPe ThIs IsN'T rAcIsT" - The Radical Right.

Except thats not what this guy was going for

What was he going for? Slave Ecconomy?
Yes they are great. Egypt. Roman. Greek. America.
Also being teached

He wanted to retell how slavery (through a lens of objectivity) was good for the economy, how slavery improved the lives of Americans.
It doesn't matter if it was good for the economy. It was wrong then, it is wrong now. Shining it in this light gives way to a slippery slope that I don't want to risk treading in this country since it is already rampant with racism.
Morality is a thing. I'm glad this ass-wipe was shut down the way he was.

Slippery Slope argument is bad.

Slavery is good for ecconomy. yes.
Automation is better for ecconomy.
Mechanical workers that don´t need breaks, food, and no incentive to keep working.

It was right then, it is wrong now, Moralities changes
The means of production changes

You have to try to look objective to figure out what is moral, not through the moral lens what is objective.
There is no objective reason for example that two man should not be able to make a vow to live their lives together

Another fallacy to look out for is syllogism: just because it was law then doesn't mean that it was right then, either. For instance, Founding Father Alexander Hamilton was opposed to slavery, even though he used them. He abhorred slavery and again, he was a founding father. It is recognized that he was not the only one with this belief. Republican Thaddeus Stevens, during the reconstruction era, was also against slavery and racism.

Just because something is law, does not make it moral. Who defines what is morally "right?" Through what lens are you looking at it?

Given the recent turn of events regarding Trump Supporters and the man himself, I do not trust people to look at slavery as "economically good." But see it as "generally good." I've been to gab.com and I have seen blatant racism on that site. I do not trust a country that is infected (to this open degree) with racism to have any pre-college education depicting slavery as "good." I just can't trust them to take things as intended.

The slippery slope argument is typically fallacious, but in this instance is backed up by precedence of civilian interpretation of official communications by our government that were allegedly intended to be benign, but were executed maliciously.

The "Good" as phrased by the representative is relative to the beholder.

Another problem this presents is dangerously normalizing two words in the same sentence that shouldn't exist together. "Slavery" and "good." It is morally wrong now and shouldn't even be presented in any such capacity as "good."

You can be objective without resorting to an appeals to emotion on this subject and still say slavery was bad, but helped the economy:

Something like this:
"Slavery in the early days of the United States was a valuable trade commodity and labor force. Slavery was also a practice which robbed people of color their inalienable human rights as we understand them today. Slaves were regularly beaten, killed, and even forced to give birth *while* working in the fields."

I'm not a textbook writer, but that covers "the good" without saying it was "good" for the economy. Just that it was a valuable commodity. It also highlights the negative aspects of slavery by stating facts in comparison to our current context as well as factual events that occurred regularly in that time.

What say you?

I am on board with that if it comes to the USA history, but linking slavery only to black people when the practice has hit all "races" over the course of history has been harmful to society.

Any mention of slavery including the enslavement of the Slavs gets your american black population to think it is about them. You have not taught them to despise the pratice because of the harm it does to people but because it is about "them". You internalise "us vs them" in your class rooms.

Given the recent turn of events I don´t trust americans neither left nor right to take things as intended. From my outside point of view you got the racist right and the racist left and liberals are pretty much dead.

Who defines what is morally "right?" Everyone themselves to their own values.
The most common morality used by people "If that was/hit me would it be bad?"
That is why we have to TRY to look at things objectively.

True enough. Yet, in the context of the conversation held between this rep and the board he spoke to, he was speaking specifically about US Slavery, not slavery across the globe.

Also, it's *taught
