I once installed Ubuntu for an 80 year old Finnish woman who escaped the Nazis as a child running across a frozen lake. This was a decade ago. She took to it like a duck to water and said it was great because it made sense, she could easily install anything and it didn’t crash. Give your dad the chance at least.
Lol by who? Octogenarian Congress members who get more bribes than emails?
The logo for Odin has a Nordic rune in it which is popular to white supremacists because the Nazis also co-opted them as symbols. They are not by nature about supremacy, they are an old alphabet.
