I'd say you see only what you want to see. You always have.
Since you have known me. About 15 years ago I thought as did you. The difference is I became better informed, and no longer able to rationalize away things which didn't fit and didn't make sense.
My Black History-Major Friend who obsessed over the Civil War and Racism was the one who talked me into believing that Lincoln deliberately engineered the civil war. He himself certainly believes that.
The Difference between he and I is that he was gleeful and chortling about it when he learned of it. I was aghast that so many deaths would have been "engineered" by someone I had previously regarded as a Hero.
Some people are born ignorant and have to educate themselves to function efficiently. And then there are some who actually get dumber as they get older. Degenerate is a case in point.

In fact, the referenced post is all about Fort Pickens near Pensacola, nothing to do with Fort Sumter, and there is nothing in the post which says anybody was ordered to attack any Confederate forces anywhere.
So it's a total, dare I use the word: non sequitur.
