Voting 'No' does not make you anti-equality or homophobic
The Government has a two-fold strategy to persuade people to vote 'Yes' to same-sex marriage. First, make this a referendum on how we feel about gay people. That's why 'Marriage Equality' will appear at the top of your ballot paper.
Normally, your referendum ballot has a neutral title (like 'Judges' Pay' or 'Oireachtas Inquiries'). You, the voter, are supposed to be sovereign. There should be no manipulation. But this time it's different. The phrase 'marriage equality' is a little message from the Government, just as you're picking up the pencil, that if you thinking of voting 'No', you're anti-equality and homophobic.
That's emotional blackmail. Most reasonable people support human equality. There is also general support for civil partnership and the rights it gives to same-sex couples. A 'No' vote won't change any of that.
