1. No - a majority of those who get off their fat arse and vote works for me. By choosing not to vote you lose your right to an opinion.
2. Of course they are not, but that's democracy for you. Most of the electorate probably wouldn't know if they had followed through after a good fart, but they still have the right to fart.
3. Why indeed but I am not convinced that those in parliament have enough moral compass to vote on anything either.
