This has been building up for a long time even before Trump won in 2016. It wasn't called DEI until recently, but it's been around a long time. It is why Trump has been running racist campaigns since 2015. What is now called "woke" used to be called "political correctness" This is not something that Trump invented. It's something of which he took advantage. And ,to be clear, the left is mostly right on these issues, but their messaging has not been good.
