Mary McAleese has become so anti-Catholic she would make Ian Paisley seem like a disgruntled altarboy.
Babies are procreated by their parents and God, the creator of all things.
Children do not get to choose their parents, nationality, or place of birth etc. Nor can they feed and protect themselves
But their parents take the responsibility to feed, clothe, and educate them. Responsible Christian parents who love their child wish for them to be washed of Original Sin, to share in the grace of Jesis Christ and to become members of His Catholic Church. They get their child baptised because for infants, this is the gateway to become children of God. She is correct in one thing, to paraphrase Tertullian, Christians are not born but made. For infants, this involves baptism in the faith of the Church.
The only bluff going on is that Mary McAleese isn't suffering from the weird and whacky Woke mind virus.
