“Please explain what is disjointed and rambling about:”
I believe I did, implictly, by parsing it. But specifically, the sentences don’t flow together. There’s no discernable line of thought. It’s one idea after another. At least one of those ideas (”no slaves were actually freed by the Emancipation Proclamation”) is baldly unsupported. Others are merely dubious.
I referenced that statement to a BING search. I even provided the link to the website I quoted as required by the rules here. So if it’s disjointed, it’s how you read or interpreted it. Go to that site and complain to them.
