If it's compulsory to take a choice of absolutes I'd say Shorten can't be fabianist - not with his current ideology. I describe him as a neo liberalist. Socialist websites regularly condemn Labor's polices. Shorten is a member of the Labor right.

Shorten is a full blown Fabian.
You obviously did not read the full list so I will post it again just for you.
