I'm afraid that personal views of what one would do contribute nothing to the debate. Every individual has the right to choose to vote in whatever way they would like to. It's not up for criticism.
And those operating the voting stations have a right to prevent people voting if they are not the individuals named in the list of electors - or if the operators are not able to compare their actual faces with the "official" faces of the electors.
This is not so that they can turn away people of the "wrong" race, sex, ability, height, weight, choice of clothing, or frequency of bathing. It is to stop anybody using someone else's vote. There would be an outcry if it were discovered that a squadron of agitators/infiltrators from a terrorist organisation, a political party with dubious ethics, or a foreign country aiming to destabilise our institutions, were to get hold of the identities of people in mental hospitals, clinics, even mortuaries, and use them to influence an election.
As someone has said, , those who forgot to bring their id, or who didn't resemble them enough to be recognised, will have learnt by the next important election that they need id to vote - and why it is necessary.
