The scary thing is how easily people are swayed by blatant lies. Britain has been let down twice recently. Both times it was the quality of the debate around the referendums.
For the voting system a lie was spread about how it isn't fair one person gets to vote once while another can vote 6 or 7 times.. this was the description of the AV system.
You then have Brexit which was a shit show. It worries me how few people ask to see evidence. This is why I do not feel people should have a say in complex decisions via referendum. If the should then Britain has demonstrated how not to do it.
