I am guessing the TA was told to go f herself. I think you have a vision of Oklahoma that is out of date. It reminds me of my wife's summer camp. She grew up Free Methodist and went to a Free Methodist summer camp/bible camp. She loved it even though she was a bit iffy about the fundamentalism. Fast forward to when I met her -- she was now UCC, very liberal, but was taking her kids to the same summer camp. They were mostly able to avoid talking about anything contentious.
Then the pandemic. Summer of 2021, I told her -- I don't think you can go back to the camp. It is going to be horrible. She was like, "I know these people, they are good." I said, "do statistics lie? Because I'm seeing that 35% of evangelicals think Covid was a conspiracy and the vaccine is mind control." "But these are my people," she said.
She and her kids came home after two days and never went back. She told me she knew I was right, but was hoping I was wrong.
Not that I know a lot about Oklahoma, but I can see the politics in that state from afar. Given the following two options, I would consider #2 to be much more likely:
1. They wanted to do something for the TA but the political pressure was too much;
2. They were glad to get rid of her and maybe had been trying for some time.
