This is a funny site about a situation I didn’t realize was so prevalent: flying the Lone Star upside down. Actually, there’s an easy way to remember that the white part is rightside up, and the red part is downside down. It’s not PC, just a fact: in the struggle to settle Texas, the whites came out on top.
Their culture was entirely incompatible with that of the nomadic Comanches and Apaches, and especially the cannibalistic Tonkawas. Texas historian T.R. Fehrenbach explained it very well: "On the frontier, it was Them or Us and They were killed so that We might live. In such wars the defeated vanish in ignominy. The winners hold out neither hope nor generosity." It wasn’t about good or bad. Only survival.

Or, if you want to be PC (or just plain simple-minded, in my case), the star points up.
Only an idiot could believe co-existence with the Injuns was possible once we left the green bosom of the Piney Woods.
That is the simplest way to remember it, I suppose. Not so politcally volatile as mine. As for idiots, they seem to be in the ascendancy these days.
I suppose I should be crass here and note that the Oklahoma flag actually says “OKLAHOMA” across the bottom, making an upside-down hoisting more obvious, but it occurs to me that they could just as easily have stenciled “THIS END UP” along the appropriate edge, but didn’t.
Interesting. I always knew Oklahoma was different, but I confess that I missed this aspect of it.
The whites of Oklahoma also came out on top, but it was nice of them, I suppose, to create a state flag that recognizes the people they vanquished for the land.

He. Reminds me that story last year, when Maariv, the Israeli daily, handed around free Israeli flags with the Independence day edition. The snag was that the (Chinese) manufacturer turned the Star of David the wrong way.
