Those who didn't vote but could of effectively decided "I don't care enough to participate. You decide for me".

If they were too lazy go out in the rain, mark a piece of paper with a pencil or use a postal vote then they can't really complain after the fact.

I'm sorry if I sound a bit annoyed, this is not directed specifically at you, I just don't like the result.

The issue was important and the voting procedure for those eligible to vote was not onerous.
