Because when normal people with critical thinking skills see a rainbow in the back of a classroom, we don’t even register it. It’s not political to us at all. It’s just a wall decoration. So why would we hone in on it? Most of us probably don’t even “see” it.

Any sign of a rainbow at all is triggering to those who lack critical thinking skills. They latch onto it and start screaming about the LGBTQ+ agenda. And they spread it to their base to fill the hate tank and get them all riled up.

Meanwhile the rest of us are like “There was a rainbow on the wall…?”
