They like the way his administration has been terrorizing brown people. Dig in with any of these ~simpletons~ undecided voters and it’s literally that simple.
I despise this current administration. Yet, when I talk to people, I treat them with the same respect as I would my own parents -- don't matter who they are. I have had fun conversations with near toothless factory workers, literal walking stereotype caricatures of MAGA guys, who really aren't bad. They're just trying to live life and keep their lives together yet here's the world, changing all around them. Then this big mouth assures them it will be all right if you vote for him. They get worked up about things like DEI, LGBTQ, foreigners, etc. Sure it sounds stupid but it is what it is, you deal with it using tact. And here I am, born and raised NYC who was a minority at my public high school (may time the only white kid in class), dated the rainbow, and have a lot of experience with a lot of culture. I usually have a hard rock/heavy metal look so I fit in and they feel comfortable. I just tell them fun or funny stories about cultures and all variety of people I knew. These stories help to clear up misconceptions. Like literally the dentally challenged MAGA fellow I mentioned before told me on my way out that he enjoyed my stories and that he learned something new about people. That's the magic -- story telling and gentile nudging of opinions. Rome wasn't built in a day.
I'm actually hopeful in my own way, but the current political environment is being shaped by adult aged children on both sides and it just gets worse. Though they always say, it gets worse before it gets better. Keep nudging that knowledge.
