If anyone ever reads this, and in light of recent blogs and the reaction to them (I.E. Anatomy of a Girl Gamer).
Here's my stance
If you take the string "gamer" and add anything in front of it, you segregate and separate yourself from that person. That also applies to "human" of course.
Our fantasy flights are supposed to be separate from the illusion of difference we impose on our everyday lives.
The important signifier is "gamer". The unimportant denominator is "girl" or "female".
If you take "girl" and "gamer" you are no longer signifying the same set as "gamer", you are giving this new signifier a new set, "girl gamer". There may be a crossover between the sets, but they are different sets.
And thats why it is harmful and stupid to call this person out for having tits and a pussy rather than tits and a dick, like the rest of us.
