(I think I must have accidentally used the "aranka" cheat code ...)
But you did fall, as I nearly did, for Gaia's statement that the topic they were discussing was sexism - it wasn't.
Fridge acknowledged the sexism of Szew's original post. He made a point of the fact that Aranka is female. I'm not interested in niche sports or chess, but I am interested in music - the analogue is when female musicians are only compared to other female musicians. Aranka's issue with this, however, was that there were stronger female chess players to which she could be compared: sexism dutifully ignored. Not every girl is a riot grrrrl.
Then, sigh, the conversation turns to the tedious realm of the gender war. "Are women better or worse at men than this or that?"
Forgetting for a moment that, due to the lack of information, any line of reasoning here is spurious, let us say that it
could be objectively stated that women are, I don't fucking know, 7% better than men at chess, on average. This wouldn't be a sexist statement, any more than it would be to say that men have broader shoulders than women. So the discussion is not about sexism.
You might argue that the impetus for the men to participate in this fruitless discussion was their misogyny. If you wanted to challenge this, you ought to have said "It matters not whether women are worse at ping-pong or what-have-you, please stop making generalisations and treat me like a human being, rather than a vagina that happens to have a person attached to it".
I hope now you understand why nobody here was challenging sexism. I don't begrudge you your mistakes, naturally you would need a man to explain these things to you.
Aranka likes to post apropos songs, so here is my new favourite band:
