My aunt literally told me “I know he’s kinda crazy, but he’s also super smart!”

You should ask her why she thinks he's smart to find out how dumb she actually is.

When she says "because he's loaded" you can point out all the stupid rich people there are in the world. Kanye West would be a good place to start. There's no shortage of examples though. Hell, if your aunt is loaded you could just hold up a mirror.
