I get everything's gotta go somewhere, but there is nothing even remotely right authoritarian about 28 Years Later.

It's a bunch of people living in a village who can all just.. do whatever. And the people we see outside that village include "Guy who just does whatever", "Family who does whatever" and "Roaming bunch of thugs". If anything the films strongly embraces ideas like humanising the enemy, the value of rejecting violence where practical, and giving a shit about disabled people. Fun films though.
