This must be real. The font choice, spelling errors, frequent use of run on sentences, and general word salad-ness are too perfectly chosen to have been faked.

I’ve received similarly written nonsensical emails (albeit lacking the racist subject matter) from my grandparents before. Therefore it’s more likely that this was typed up by one of the grandparents.

Based on the use of Jokerman, all-caps, and exclamation points, I’d say a grandmother wrote this.
