Agreed, and don't be disheartened. There are a few topics on HN that bring out comments and voting that are surprising and confusing to me, and this is one of them.

In this case, I have a sense that a certain generalization is very present in society, and harmful (e.g., a barrier to solving problems of injustice, or otherwise adversely affects how we treat each other). Someone might be speaking of their own anecdotal experience, and upset about that, and not thinking about why it might be important not to make blanket generalizations from that.
