The worst thing about Trump is that he normalizes all the worst things—corruption, extremism, and extreme partisanship, among others.
Take the Bitcoin scheme he's running as president. It makes the news, yet no one seems to care or even bat an eye. During his first term, at least he pretended to divest from his businesses.
He talks about imperialism as if it's justified. But if it's acceptable to take over Greenland, Canada, or Gaza, what's to stop China or any other country from believing they can do the same? This kind of rhetoric is dangerous and should never be encouraged.
Remember when Trump claimed he had nothing to do with Project 2025? Well, most of his executive orders align with it. On top of that, the project's author now holds a powerful position in the executive branch. It's deceitful and represents extreme partisanship at its worst.
Additionally, all the filth, rot, and decay within the U.S. have the power to influence other countries as well because the U.S. looms large on the world stage.
