'Why such a fuss about gay marriage?' asks Mrs Brown
The nation's favourite matriarch Agnes Brown has joined the Yes Campaign in the lead-up the Marriage Equality Referendum.
In a online video Mrs Brown, played by actor Brendan O'Carroll, urges viewers to vote for marriage equality on May 22.
The video has been viewed close to 20,000 since it was uploaded yesterday.
"Nothing beats the joy and contentment I feel knowing that my son Rory has just as much opportunity for happiness as everybody else's son," Mrs Brown says.
"And that's all I ask for him, the opportunity.
"When two people love each other, you should allow them to get married.
"What's all the f***ing fuss?" she asks.
Comedian Brendan O'Carroll likens the current opposition to gay marriage to past hostility towards interracial marriages.
Mrs Brown asks if people will look back years from now on this moment with "jolly disbelief at a time when people of the same sex could not marry?"
And she notes there was once a time when Catholics couldn't marry Protestants and a time when women were not allowed to vote.
Rory Cowan launched the video at the Yes Equality shop in St Stephen's Green Shopping Centre in Dublin.
"Attitudes towards homosexuality have changed so much in Ireland," he said. "When I was a young man, gay men didn't hold hands in public and that has changed completely.
"I hope people will vote Yes in this coming referendum. Gay people don't want to change marriage, we just want to avail of it.
"We are a fabulous country and I think we are ready for this."
The group Mothers and Fathers Matter also launched a video campaign yesterday called, "Make up your own mind".
It urges voters to resist "attempts at emotional blackmail", and to consider the issue according to their own consciences before casting their vote.
They claimed people are "frightened to speak out about their concerns".
A spokesperson said "real and serious concerns" exist about issues such as "conscientious objection".
