For the information of the world:
1 - I am NOT a basketball player. Just because I'm unusually tall does not mean I've chosen to spend my valuable time in utter waste. Maybe you're short; do you play miniature Golf? How about Monopoly? No? May I suggest playing Clue-less? The next time I get this, I'm going to ram said person's teeth into their small intestine. (Or wait, I know! I'll say next time, as long as he's male, "No, I practice self-defense and martial arts. Now since you've annoyed me so, may I ask your permission to try this method I once learned call the grab and rip?")
2 - I am NOT a "computer geek". Just because I wear glasses and am a white guy who doesn't have tattoos or a mohawk does not mean that I debauch myself with machines and electronics anymore than I already have to. True, a progression is natural and desirable, and man will always seek to best his own creations, but the current state of our world and our reliance on whatever new Jobsian trinket is on the market disgusts me to no end. Why have I been getting this one so much lately?
3 - This one I get less, but I do get it occasionally. I am NOT Mormon! People who might see me not in all black can say this (opposed to the fear and arm's-length treatment I get when I do wear it; the older people occasionally think I'm Goth, but the younger generations know that I'm not--instead, I befuddle them so, and they fail to satisfactorily classify me), or who see me as an unusual or religious young man, or (almost always) when they discover the horrific and shocking fact that I actually want a few children someday. A month or two back, this woman I have never met stops me and proclaims loudly, "You look familiar!" She stops to think intently, then a light goes on in her head (or not, depending on how you look at it). "I know! Are you Mormon?" she asks. "You look just like one of those guys that comes to my house!"
Seriously, what's with this look thing? Heck yes, I know stereotyping can work to amazing effect (try it one type, in a non-negative way, the test the person; you'll be interested at what you come up with), but come on, do I give any indication of any of these groups? Just how stupid are people today?
Next time I'm out and about, maybe I'll go up to a black man and ask, "Hey man, are you a gang-banger?"
Is this fair? Proper? Respectable? Acceptable?
I sez...nope. (But mostly, it's massively annoying, particularly the part where my smiling face feels like a plastic Barbie doll's....)
