Ok, if you say you are 51 then I will take you at your word.
You showed pictures and didn't really think they were taken before theCivil War but thought you could combine the two things Since the South had slaves.
So you knew theses were supposed to be under the flag of the US.
At your age though you don't talk like you actually know anything about what you can imagine from pics.
So let me confess, I wasn't here for pre civil war years either but I have heard some history teachers say the antebellum part of our history has not always been taught correctly.
I know someones great grandfather in central Texas grew cotton and had a few black families living on his place as employees after the war was over. When the KKK went out riding over some offense he took his people out to the flats and stayed with them to hide them. He left his wife and children to sit quietly and wait for morning. One of his daughters told what it was like to hear the horses hooves go by the farm.
But let's talk about a few years ago, ok?
An electrical engineer was working at Texas Instruments and when on a
Certain project was working with among others a Jewish man who was also an EE. But this Jewish man was treated poorly, often looked at disdainfully, occasionally insulted and berated at every opportunity. Not by American EEs but by one EE from Afghanistan. There was also an EE who was a Chinese woman! Very smart, always treated like a second class citizen , made to do more work than others, carry more than her load - never by American EEs - but do you care since she took it like she thought it was normal?
Last and maybe least - one pic some time ago was photoshopped and put on the internet. I know you trust your source and would never imagine anyone doing an evil stunt with horrible pics.
But
all your pics can be replaced by horrible pictures that are very real and are much more recent in time - and can be verified. Should anyone want to see them either? I don't.
Do you have a point?
I understand there is racism, bigotry, etc. today. There will always be.
The subject is flying a flag that symbolizes racial hatred on government property.
