the words hey?
Well i've probably got that worked out already? I pass 100% on the web, sometimes when i'm not even trying. The only time i'm picked as a female is when i've picked a female avitar or said something obvious like "how do i hold my bass without my tits getting in the way".
I almost alwayse go as a guy on-line (it's the only place i can pass so i feel i should take advantage), except sites where i'm interracting with people who've seen me in person, or there was one site where i was talking a lot about women's health and i thought it would seem weird to know so much as a guy.
I guess some of it is my interests, for some reason (long story) i was looking at the genders on the profiles of one of the sites i've been on a lot and they were all male. Guess that's why they assumed i was one of the guys? they were even saying things like "sorry Sir, but you are wrong" and "(about me) i think what the original poster meant by his question was..." I liked that

I also really liked it once when while i was stull pretty much a kid i sent a letter of complaint to a TV station with my phone-number as a contact. I signed it with just my surname and innitials. They rang my house and asked for Mr. (Surname) and confused the heck out of my dad for a while untill they worked out it was me who wrote the letter. I wonder why they picked Mr? I wonder whether it was my writing style or whether it was just they figurred they wanted to use a title and Mr would be more offended by bing called Ms than a Ms would be by being caolled Mr?
Actually some of the F2Ms here seem to have a certain female vibe to what they say, but maybe i'm just kidding myself since i know their history.
...and yeah, it's definately not just pitch, heavy metal vocalists often do some very high-pitched screams which are still distinctly male. The same pitch from a woman would have a "maiden in destress" or "screatching hag" vibe.
like rob Halford
Judas Priest - Dissident Aggressori think there's a touch of "studio majic" on that first wail, but some of it's organic
or halford about 35 years after that first recording...
JUDAS PRIEST - THE RIPPER^ that's not his best performance, but it's definately not feminine dsespite the pitch
or even Alchemist (about 1 minute 27 seconds in)
Alchemist...Chinese Whispers
