No I don’t understand why he’s wrestling with it.
If the process of democracy is compromised, either through loss of earned representation, loss of fair voting, or loss of free political speech...then the only resolution is violence.
Open voting is not fair voting. If voting to join a union is not private, then I will physically prevent union reps from conducting such a vote. If they can be unfair, then so can I.
So, you see, you DO understand why Sen Sphincter might have second thougths about it.
