I woke up about 5am with a sudden realisation – why is it OK to say you don't like children but not to say you don't like black people? It's just raw prejudice. If you don't want to have any that's fine, it's your choice, but if you dislike children themselves please keep your thoughts to yourself!
It doesn't even make any sense – I've never been gay or black or un-british, but I have clear memories of being a child (and I had equal lack of choice about the matter). I'll admit there are things about myself as a child I dislike – I was selfish, violent and bad tempered, but to some extent I have grown out of those things – and there's no way to get here without being there first.
