Often on HN there's some discussion and people feel that they can tell other people what they should be doing about some subjective thing.

One example is this thread. Some people don't like to party. The commenter said that we should go and party. Even if we don't like it. We should all like what they like and we should all do what they want to do. That's a brilliant example of the kind of pushy asshole I don't like to meet at parties. It's like those people that try to force you to dance at weddings. I don't like to dance - that's my decision.

Another recent example was mother's day. I don't like my mother. She seriously neglected me as a child until I was removed by the state, which still causes me medical problems to this day. But everyone feels entitled to say that I should call my mother to say hi. Why should I? Because they have a good relationship with their mother? Good for them. But don't tell me what I should or shouldn't do.
