Outdated or not, that mindset was inappropriate then and it's inappropriate today. Granted I don't necessarily expect kids in college to know how to behave, but it isn't cool to be a dick to people just because they use one OS or the other. It's especially sad when you consider that these are a bunch of nerds, who know what it's like to be a social outcast, and then turn around and inflict that on one of their own.
