I assume we are talking about this chap.
Re his sacking - I imagine it might be frustrating in a role like that but you are employed to disseminate the views and edicts of your employer no matter what you personally think. If you can't manage that maybe that’s not the job for you.
Re the kids thing - I think I agree. People only have children for 100% selfish reasons (wanting to get to play at being parents, continuing their "blood line", having someone to wipe their arse when they are old and wrinkly, etc) and I happen to agree with him that the world would be a better place with a smaller number of us on it. That requires us having less kids per family. Lots of economists will tell us that the world would fall apart with less people to grease the wheels, but we have coped in the past and I'm sure we can do it in the future.
