based on such marriages, as "grotesque nonsense." Following this, Iona director David Quinn tweeted "Proposed change to marriage 'grotesque nonsense'. ...Great letter by Prof John A Murphy in @IrishTimes today." Quinn was criticised for this tweet by LGBT rights activist Panti, who wrote: "I can think of lots of things that are grotesque. Extending constitutional protection to all families is not one of them. ...I would call it 'fair', 'reasonable', 'compassionate', 'considerate', 'respectful', or even 'the very least we can do'.

Marital breakdown claims An Iona Institute report called "The Fragmenting Family" drew heavily on data from the 2006 census and said that between 1986 and 2006 marital breakdown in Ireland rose by 500%.

Issues were subsequently raised in the Irish Senate as to the accuracy of the report and a response by Carol Emig, president of Child Trends, wrote to the convention and stated that "This Child Trends brief summarizes research conducted prior to 2002, when neither same-sex parents nor adopted parents were identified in large national surveys. Therefore, no conclusions can be drawn from this research about the well-being of children raised by same-sex partners or adoptive parents." Tax In 2007 the Institute issued a policy document entitled Tax Individualisation: Time for a Critical Treatment which criticised the government's policy of tax individualisation for married couples as favoring women who choose to work over those who stay at home. The document claimed that families where only one parent stayed at home were discriminated against by the current tax individualisation policy. In May 2011, the
