Considering that it's already illegal to force students to recite the Pledge of Allegiance, or even stand for it, this is at best idiotic, and at worst, a gateway to overturning the bit about the Pledge and opening the gates to political indoctrination of children.
Right-wing performative patriotism is there to stop people from thinking that their country could be better, because of course it's already the best.
Actual patriotism is the act of improving your home to be worthy of pride.
Remember when conservatives were freaking out at Colin Kaepernick because he wasn't doing the performance right? Because he was trying to bring attention to the plight of black folks in our country? It's because they confuse nationalism with patriotism; they were pissed at Kaepernick for "hating America," when he was saying "we should be better."
The nationalists don't want to country to work for everyone though.
