Wow, what an ass.
Believe it or not, it is quite plausible that the explanation "You are simply too short for me" is the whole story. Many girls -- and guys, for that matter -- have "dealbreakers" which can torpedo an otherwise worthy candidate. I'm not one to judge whether having dealbreakers is a good thing or a bad thing, but the phenomenon is quite real. Refusing to date someone who is addicted to heroin? Probably a good, sane limitation. Refusing to date someone who is anything but a blonde? Probably a stupid restriction. Refusing to date someone with kids? Dunno.
Everyone has certain buttons which have to be pressed in order to find a particular someone attractive, and not all of them make sense. Or, sometimes you just need a set of guidelines to narrow the field since you can't date EVERYONE. The bottom line is that people DO have cutoff criteria, and they use them every day.
I don't know The Shadow personally, but judging from his behavior on the boards over the last couple of years, I'm strongly inclined to believe that his version of the story is correct: she couldn't get over his height, wasn't attracted for that reason, and dated someone else. I can only assume from your response that you have some kind of personal issue with him to insult him in the way that you did...which is pretty fucking sad.
