The female human dance is one of my favourite dances in the game, so I made my warlock a human female. I had originally made a male exo for my warlock, but I got over it by level 8 and deleted it. My hunter was made before the warlock, but since I already had the plan to make a male exo, I decided my awoken would be female. My primary is a male human titan, he's my 'avatar character', made to represent me in Destiny. Both my secondary characters are just there for me to experience the other classes, have extra opportunities to earn weekly rewards (nightfall, raid, weekly heroic), get the sub-class achievements and have a use for all those random hunter/warlock gear drops I got. That's it. They're not some attempt to troll, a misplaced sense of 'gender identity' or some other wild theory as to why guys play female characters. I spend most of my time playing as a male character, so when I swap to another character it shouldn't feel like I'm just playing the same character with different abilities. I'll probably end up deleting the hunter and warlock when I'm less interested in playing multiple characters, and just focus on my titan, the only one of my characters that matters to me, who is a guy. I agree with you OP in that a character in a game does not equate to an expression of gender identity.
