I politely want to say shut up, but can't find best words. Because you judge people based on their sex/race, I am pretty sure Redis people didn't even think about sex of judges, they just selected people by their expertise. There might have been other female experts on team, but they weren't considered not because they are female, just because other people had more experience (may be)

No one said women are incompetent, this is how you build your own world view, so you think men think women are incompetent.
