ok, let me run you through my thought process at that point in time.
First off, I picked gnome for obvious reasons (their racial traits highly outweigh that of anything else a warlock can be)
Second, who wants to be staring at a guys ass all day? Not me.
Third, who gives a fuck if your character is a guy or a girl, I am NOT on a PvPRP or RP server.
Health and mana are pretty much interchangable with a Warlock. I have a Gnome Warlock too, though, so I won't argue this point. I definitely see your logic (though escape artist SUCKS hardcore compared to perception. IMO, perception is the best racial ability next to WotF for PvP).
To address your second point, I must say that I completely agree. That's why both of my main-ish characters are female. My Warlock is a male, but I haven't played it for months for more than ten minutes. As you probably know from my endless ranting, I have a Human female Rogue and a Human female Priest (49 and 60, respectively).
Second, I hate playing a female character almost as much as I do staring at an animated manass for hours on end. It's annoying when you get guys hitting on you. I usually tell them to just fuck off, but if you've grown to like them or respect their abilities, it's hard to be stern or put it in a nice way.
Gnome females are nasty, but oh well. I was just giving you a hard time to begin with.
