That's so weird to me. I grew up in an area of Texas that is very red today. We quit both pledges in the 3rd or 4th grade. It's weird that we did it at all, but that was back when they also taught that freedom of the individual was super important and if you didn't like what someone else was doing you could always just look away because it wasn't your fucking business. So they didn't make us do it at a certain point because it was counter to the other shit they said. That was in the years leading up to Ann Richards being voted as governor so that may inform outsiders of what was happening at the time.

There's a lot of problematic shit that happened when I was a kid. Don't get me wrong. But at least they seemed to be headed the right direction at the time with the info we had (that's a whole other ball of garbage that I'm not picking at today...ask me another time when it's not 3am). I had forgotten about both pledges as an adult until someone reminded me a few years ago that it was a thing.

Texas has gotten way more idiotic over the last 30 odd years.
