David Attenborough. I have a completely irrational hatred of this national treasure.
"I've had the privilege of travelling all around the world and seeing the most amazing things for decades... but YOU mustn't go anywhere anymore, because of climate change".
It makes me think of Prince Philip and James Lovelock, preaching earnestly about the dangers of over-population and how we must all act drastically and make stark sacrifices in order to keep the planet from falling off a population precipice... except for them of course, who were both fathers of four children.
I've only got one child, so it doesn't affect me personally; and I have no problem at all with people who choose to have a big family - except for the ones who do so but then tell everybody else that they mustn't.
