The obvious response is - if you don't play the game, don't try and make the rules.
The Pope has a vested interest in children being born to Catholics, hopefully it will stem the decline in Catholicism - which of course his church does absolutely nothing to reverse, living its medeaval ritualistic life supervised by emotionally retarded men and women.
I think children are a blessing, but they are not compulsory, and they are certainly not for everyone.
Thankfully the pressure from society - oh, when you will ne getting married then ... when will we hear the patter of tiny feet ... when are you making me a grannie ... is decreasing with each generation, and the feelings of guilt pressed onto individuals who simply don't want to have children are being lessened as well.
There are far too many people who bow to pressure to have children, without thinking through the responsibilities and the commitment involved, and if that is reduced, then that has to be a good thing for all concerned.
I don't take a lot of notice of what the Pope says, he has nothing to say that I would wish to hear.
