Free ID would be a small step to answering the main concerns - but just a small one.
On your second point, the only person I remember advocating a second Brexit vote solely on the grounds that he wanted a second go was Nigel Farage - on the night of the referendum when he thought his side had lost. All other calls for a second referendum were on the basis that the first one was a blind vote on the principle; a second vote would be on the detailed 'offer'. I didn't (and don't) support a second referendum, but I do like a bit of honesty in how the case is presented.
Basically you're putting up calls for more democracy as a counter argument to prospective moves that would suppress votes in an election (or referendum). Given that I will take all your comments with more than a pinch of salt!
