I'm not disagreeing with her opinion or negating her experiences, it's not my place. That said, classical (3h+) isn't the only form of chess, and it could be something that is personal to her and not representative of female players as a monolith.
Logically speaking, it's still a disadvantage even if it's one that matters less in some scenarios. Gender is highly predictive of a lot of biological statistics. Truly, we should be basing brackets on the biological stats themselves and make gender segregation a thing of the past. How will people react when the brackets reflect genetic potential rather than gender potential? Probably just as oppositional. People hate being told that someone else has a higher potential than them even if it's true. I don't blame them. But we can't live in a reality where we pretend that some aren't better built for certain endeavors.
