I tried a female character once in Wow like back in Vanilla? Way before I was an RPer. That was the only time I ever did. I never RP or in fact even play as a female character, so I've never posed as one. It doesn't sit well with me and I feel uncomfortable even playing as one. While in the past it bothered me when other people did it too, that's not the case anymore. Nowadays you'll only see me rant when my girlfriend suddenly says she wants to play a male worgen because female ones look derpy. I also always presume it's a guy behind a female character until proven otherwise, and usually, that is the case.
The few times I allow myself to be surprised is when it's a girl behind a male character, but that's about it. Eitherway, neither gets special treatment from me. That, and the more they try to act all "I'm a girl, give me special treatment, why won't you like me." I only start to loathe them. I remember the last time a girl in WoW tried to use me as a tool very vividly. It was in Nagrand, and apparently she thought it would be alright if I let her kill me in the PvP grounds there for tokens over and over again. I merely told my friends about it on Horde side, and as she had PvP on, you can imagine about 10 people storming one druid whose busy trying to slowly kill me. My sides hurt after that, more so because I convinced her to respawn and then they killed her again for good measure. Good times. Never spoke to her again.
