Laughable response from the right: "But the journalist was talking to Murray, who's a man, so of course he just meant male players! There was no mistake, Murray just bad."
Yeah okay. Lets change the roles up then. Journalist is talking to some white tennis player and says: "Your opponent was the first person since 2009 to reach the semi-finals..." Then the tennis player corrects the journalist: "First white person," because a black player had reached the semi-finals 5 times since 2009. Would it not be racism then? It would be, casual and ignorant and unintentional maybe, but racism nonetheless. Just as this is sexism here. Completely ignoring the accomplishments of women/minorities and acting as if "tennis player" means "male/white tennis player" by default is dumb.
All that said, some journalist being dumb and saying something sexist is hardly worth our time or outrage. Afaik nobody was directly or intentionally hurt by the journalist. Nor does there seem to be much of a link between his idiocy and the much worse acts of sexism which are perpetrated daily. It's good to criticise the dumb journalist but he probably doesn't deserve too much of our time or attention. Life is short and time is limited after all, our attention is a valuable commodity, maybe we should direct our efforts towards more important things. I'm aware of the irony of that statement after a relatively long post but whatever. If people talked as much about becoming vegetarian to stop climate change and world hunger then the world would likely be a much better place
Edit: To reverse the situation to something even more ridiculous, imagine if the US decided to make another moon landing but this time with women. Imagine if, when those women were interviewed, they were asked: "How does it feel to be the first humans to walk on the moon?" It would be a completely moronic question and the error is of the same kind -- though it's not of the same magnitude obviously. Really can't believe there are people out there trying to say the journalist didn't make a mistake lol
