Side question: why would having a male or female mascot be "a message in itself"? Why do people want to see a message, and especially a $currentDayPolitics one, in every single thing? A mascot can be a cute mascot without having to represent anything more than exactly that.
Just as a random example: Let's say some OG founder of a project had a cute dog named Laila, and the project makes this dog its mascot. Why should that be a problem, AT ALL?
And what's even worse, if you think this "everything has a message and we have to be super careful what the message is" thing through, the conclusion is: No project ever again can have a solely male or female mascot. Which is of course absurd.
And this whole "we need to send the RIGHT message" thing falls apart with time anyway, because what the right message is, WILL change over time. You're not at the end of all human enlightenment.
Like, most mascots aren't in gendered pairs normally (like your dog example!), you just have 1 option to represent the thing. People see Laila the dog and think "oh yeah, LailaOS".
But given you have 2 mascots, with 1 being pretty ambiguous, but the other being dressed in a pink dress with bows, it does mean you probably want to use both when presenting KDE, just so you're not accidentally saying "this is the KDE event for men" or "this is the KDE event for women". If you made your mascot the AIGA bathroom symbols, you'd have the same issue.
My thinking about the "right" message is just that... I don't think that's what they want to tell people right now, in our current time. Everyone can use KDE. It's not a historical impact sort of thing.
Again, not a huge issue really. Just seems practical. Hopefully I'm getting that across. Sorry if I'm not.
