Thing is, the best vessel for that might be pop culture - Cory Doctorows books convey the issues of surveilance state to the general public way better than any kind of preaching does.
The issue, I think, is that mostly the issues are focusing on fringe activities which aren't approved by most of society (sexting, "hiding things") instead of taking lessons from history of our socialist countries and other widespread abuses of governmental power. We already had surveilance society and it sucked even for people who didn't do anything wrong - we need to repeat those lessons more. Especially since it seems that history in schools seems to be failing at that.
There is too much complacency and faith in our democracy in the UK. No one really believes a despot will get into power, despite it happening in recent history to similar european countries.
