I'll take an honest stab at this assessment and say that the character did not fit the common stereotypes about disability. Please correct me if I'm wrong. From my observation as a regular viewer of the show Artie Abrams is not:
- pitiable and pathetic
- an object of violence
- sinister or evil
- "atmosphere"
- a "supercrip
- his worst enemy
- a burden
- a loner
- incapable of fully participating in everyday life
Artie Abrams in the show is:
- honest and caring
- fully aware of his disability and uses it as a strength
- upfront and center stage as a key main character (not a background character)
- in a relationship (the show addresses asexuality, Artie 'had' sex with his girlfriend)
- present in all major scenes even in a wheelchair (he is given major stage time as an active participant - dancer and singer - in all performances)
