Same sex marriage will shut off freedom of expression

I think that a referendum is a good thing, as long as it’s an informed one. Let the electorate decide and whatever the majority desires will be passed into law, or into the Constitution in this case. Such is the way of democracy.
There is a fly in the ointment though. The thing is that in order for democracy to work the electorate should be able to inform themselves and to speak freely and discuss the issues at hand.
