TÁNAISTE Joan Burton has insisted the same-sex marriage referendum will not curb family protections despite an influential Islamic group warning a 'Yes' vote could "open the door to new definitions of marriage, which could extend to incest".
The Irish Islamic Centre (IIC) published detailed advice to Muslims on the referendum.
The advice on the May 22 vote said the Koran warned that homosexuality is a serious sin.
"As Muslims we believe homosexuality is dangerous for the health and for society, as it threatens the foundation of the society which is the family.
"The amendment will have serious consequences, as it will redefine marriage and parenthood. It will open the door to new definitions of marriage, which could extend to incest," said the IIC. "These are consequences (for) children and future generations."
IIC founder Shaykh Dr-Muhammad Umar Al-Qadri said all Irish Muslims had a duty to vote next month.
However, the Tánaiste challenged the family threat claims.
"The rules of marriage in Ireland (won't change). There are regulations and inhibitions under our law in relation to consanguinity - which is blood ties - and, secondly, affinity - which is relationships that may exist in a family through marriage such as a sister-in-law, father-in-law and so on."
