If we want to be fair to Daniel Fox, maybe he meant that there are no differences in the game regarding attributes and character classes the character is allowed to play as.
Still, that is a bit boring mindset. Part of playing a character of a certain gender is to embrace, or break, the stereotype associated with it.
Once I played a -I guess it would be called a genderfluid- character who used magic to transform between male and female forms depending on how he/she felt at the time. As a man I played him as a introverted emotionally cold rational logical thinker who preferred ranged weapons and used magic to boost his weapon.
As a woman I played her as a extroverted charismatic, funny flirty tease who in combat used her magic to buff up her attributes and fight in melee.
The character was brought up and trained as a spy/assassin since birth and had been able to change sex since puberty. Because it is a great ability to infiltrate somewhere. Due to brainwashing and emotional trauma, he/she no longer remembered what sex he/she was originally born with. When the magic wore off, the character returned to a sexless, androgynus, infertile body.
I don't know if that gives me, or removes, Woke points.
