Rainbows were commonplace on everything related to kids; always on their toys, one of the first things they learn to draw to help understand the colour spectrum. They've been strongly featured in both children's films and books, as well as usually found on some charities' logos.
The hijacking of the rainbow on behalf of the progressives has probably been done subliminally to psyop kids towards it.
It's possibly the most nefarious thing they could have done. In the Bible it's known as God's promise to Noah that the Earth will never be destroyed in a great flood again. They robbed the symbol from children by removing one color from it: making it 6 rather than 7, and they now only associate it with butts and pride. Pure evil. I wish there was a way to sue these people so they could never use the symbol again somehow. Kind of like how the World Wildlife Fund sued WWF -Vince McMahon, and they can't use that symbol ever again.
