I had the same thought and am fairly confused by the outrage.

Isn’t the whole joke that as soon as we sit down to nerd out on Linux that we put on our frilly socks? There’s even the whole unixsocks comm dedicated to it. And it always felt good in a throwback to the 90s ‘outcast geek’ community without all the cis dude-by-default baggage bit of in-joking. Welcoming all our brothers and sisters by highlighting just how much they are part of our community.

What does OP think the image suggests I wonder?
