Alphabetist 

Someone who is prejudiced against people who's names start with a letter near the end of the alphabet.

"Man we always get stuck at the end of the line, it sucks."
"Ya man. Its cause our names start in W and Y, and everyone here is a damn alphabetist."

Alphabeticism 

Discrimination based on letters of the alphabet

My teacher let all students with ‘A’ names go to recess first instead of choosing the good kids. She’s alphabeticist. That’s alphabeticism.
