Your assumption that the room was full of men and one female recruiter perpetuates gender inequality as much as your assertion that everyone should refrain from good natured ribbing at ridiculous requirements just because the person dictating the requirements is a woman.
Gender inequality in tech is a much deeper issue that starts much earlier in life. And it's possible the ridiculous requirement of 12 years of kubernetes itself perpetuates the issue because it immediately preferences people who came up with the OG attitude.
At first approach I wanted to agree with you, but after trying to imagine a room full of women vocally laughing at a male recruiter who’s made a similar mistake I must concede that the matter is not so black and white.
