I thought it was a funny joke. You have to remember he's a psychologist. When it comes to children they think very simply in terms of reward and punishment to "train" children to learn to behave. You should've seen that from everything else he said about his interactions with children. I don't know how you can also come away with that psychoanalysis of him, I'd say you're reading into it too much. In reality, we are human and small things tend to irritate the majority of us from time to time. I'd also add that aggression is a tool that has certain uses throughout life, you can't always live life on the defensive. Young adults of any gender should be told that this is a tool at your disposal and completely okay to use at certain times.
For the lobster thing, I read it as neutral information. I took it as he was bringing up a similarity he has observed between the lobster behavior and popular plots in entertainment that seem to be popular with certain types of women. He's just presenting a connection for readers to make up their own minds about rather than stating some fact. However I also think most young men who read that will tend to agree with him quite easily, it definitely feels like it could partially be true (bad boy stereotype is a thing isn't it?). Also would you consider yourself in general to be a 'usual' female compared to the general population say personality wise or any other metric even? Just being on HN tells me you're already unusual, wouldn't you say?
