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.
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.
I hated windows 95/98, it broke all the time. The dudes in the doom community in IRC were like hey Linux is cool, try that. Never looked back. From what I hear from my friends and family, windows still sucks all the time.
