A legal minimum age to be exposed to religion is just one of the proposals of The People’s Manifiesto by Mark Thomas.
The book is a hilarious compilation of spontaneous proposals by the audience of Mark Thomas radio shows. They are ideas of people who think that they can do a better job than the politicians
that represent them.
Some of the policies would, if enforced, result in the end of the civilisation as we know it, like making party political manifestos legally binding or ending tax havens, including the many British ones (and bomb Switzerland). Other are deceptively simple like legalising all drugs or enforcing that members of parliament have no other job than, well members of parliament.
I go for these two: the right to use a product without having to reference a user manual and the opt-out system for organ donations.
