The reason the person you're imagining is a one-trick-pony with no thoughts beyond claiming oppression is that you're the one imagining them that way. This isn't a real specific person, it's a caricature in your head of the worst traits of a few people, that's applied to a group many times larger.

Cant speak for OP, but I do know specific people just like that. Too many actually. I think far too many introverts on HN imagine everyone else only knows a handful of people and think people only know other like minded individuals. Outside of the tech industry, it's very common for people to interact with a wide diversity of people.
