Howdy! Hah, my picture IS super goofy right now. I put a more normal one here so I wouldn't freak you guys out.
I'm the Seattle online dating coach Mochi mentioned, and I'm happy to chime in and answer any questions that pop up. (You don't need to hire me to ask!)
Short take: the BMI requirements thing is a super douchey statement, but if you think about it, you probably have similarly shallow dealbreakers that just aren't as controversial to explicitly list. Like, you're probably kind of picky about height, body type, and maybe hair/eye color or even race, whether you publicly admit it or not. There's nothing wrong with having those preferences to a certain extent—to each their own; people are allowed to pursue what they're most attracted to—but the act of listing it is what comes off as so awful. That said, most guys don't realize when they're being asses, heh. Most women don't either.
This guy seems not worth your time. But in theory, if everything else about a guy seemed not terrible except this one jaded-seeming picky statement, and you actually fit within his desired BMI range and he seemed to fit within your own attraction standards, I feel like sending a message feeling it out might be worth your while. Something like "so, how many women are excited to go out with you after they read your BMI requirements, and how many tell you to get lost? It's for a research paper I'm writing. :P" You could always see what he came back with, you know? If he's a tool about it, there you go; no time wasted. If he's a little sheepish or guilty sounding, maybe he's just a decent person with a specific attraction profile who's not that good at this whole online dating game. In which case it might be worth getting coffee to see if he seems like he has terrible judgment in general, or just about what he writes in that last OKC section.
Oh, and PS: I really appreciate the possibly accidental candor about my goofy site pic! Believe it or not, having something less formal makes it easier for many potential clients (mostly geeky guys) to feel comfortable reaching out to me for an initial consult—but it's totally a placeholder. I'm working on getting a more professional shot done and my shoot is NEXT WEEK! I'm just as nervous as my clients usually are before their online dating photo shoots.
