This is terrible news for the monodextrous gender unfussy person. It's bad enough having queers tell you that you don't exist, now I'll have to put up with ambidextrous bisexuals telling me I'm not really one of them, either.
I'm bisexual and mostly ambidextrous - I can't write left handed very well, but can do everything else. I'm not hyperactive (quite the opposite), asthmatic or dyslexic. However, I suffer from dyscalculia, dyslexia's lesser known sibling (is it any wonder I hate math?).
There are several lefties in the family including a cousin most of us suspect is gay (not that there's anything wrong with that).
Okay, I haven't read the article, but I can't help but wonder if they actually found that self-identified ambidextrous people are more likely to be self-identified bisexuals. Maybe I'll go read the thing now.
