It's not a "mere mention of men" it's some bullshit nonsense that implies men ought to be a certain way and it also subtly implies that we're all men here and that this is no place for women. Christ you are thick.
Did you consider that it is such a subtle implication (your words) that maybe there is no implication there at all? I just ask because that implication doesn't exist anywhere in the actual quote (word for word), so plausibly it is your own baggage that added it to your reading.
You effectively created your own sexism and then got mad at that very same sexism. Maybe you should self-reflect on that a bit after you've calmed down.
