There are nuances and vagaries of history that so complicate these issues that there can never be a "correct" version of this story. It can safely be said that the conventional wisdom is caca, however.
So far, the Lone Star Flag has successfully avoided the stigma that has consumed the Star and Bars. There is enough "other" history to Texas that it is not yet tainted with the Confederate's "great sins" but in this current climate of resurgent Mexican claims to the lands ceded in the Mexican American war I don't expect that to last.
Trying a different one ...
I know, I cringe at what has happened to the Stars & Bars. It's just not right. I have many positive feelings when I see it and have a few things that contain the image. I don't think "slavery" when I see it at all. But, of course, I *wouldn't.* (So *they* say.)
Sort of like the word "plantation" and what Hillary turned that into - or stepped (and fetched) it up to, anyway. I still think of plantations as beautiful "farms" with lovely grounds and stately trees and lots of moss. Sometimes, a Caribbean tropical "farm" with banana trees and a lovely main house.
People see what they want to see, I suppose. If the Lone Star or Bonnie Blue comes under fire, we'll "blame it on Florida," since it was theirs first, lol. No, wait, a Texan would *never* admit that. I guess we'll just sew us up some Bonnie Blue do rags and carry our "banners high" into the street war, if need be.
