I mean, it jumped out me because ginger and blonde are both the two rarest hair colors and the ones more or less exclusive to people of European descent, but I also don't really want to waste energy debating someone who thinks it's "clownish" to note someone's race and gender in tandem, because we're clearly never gonna see eye-to-eye on this.
It is kinda clownish to note that the coworkers are white males when it's followed by the fact that they're all room mates. What is the comment trying to draw attention to? Are they trying to highlight the fact that hiring is biased toward recommendations from employees? Then why mention the sex/race? Is it evidence of "structural imbalances as they exist in society right now" that three white males live in the same apartment in bay area?
So yeah, I guess it was the most important thing.
