Re: You are an idiot, truly speaking out of your arse.
To be valid it would need to be the true spelling of her name. The two spellings you used: Guinn and Guinne are manifestly not how le Guin spells her name and therefore cannot be valid. You would only need to make an assumption about how to spell her name if you had only heard, but never read it. Both Destroy All Monsters and myself managed to spell Ursula K le Guin's name as she spells it.
I think it's fairly safe to assume you are illiterate and irrational.
