But it's not forcing identities, or it wasn't back in the day.
Were you black? It didn't matter. White? So what. Male? Female? It didn't matter.
The words on the screen, and the thoughts behind the superficial bodily stuff was what mattered. How did they think? How did they communicate their ideas? How did they collaborate? What were their ethics and values? -- Those were what mattered, not that someone had a blue mohawk and were bisexual. Those things didn't matter.
Better yet, this method also transcended poor and rich... Yes, you had to have a certain amount to access a computer and the internet. Or you hacked the local university's access. Or used it at the library. Or had a cool friend. Except, now it's what you think, not what stylish clothes you wore, or the jewelry you had.
And this blurring of gender, sexual preference, race, weight, height,.. you name it was distilled down to "what's in that skull". And someone whom you might never walk up to and talk with, you could strike conversations with them, and they you. It also was the first steps of breaking down national borders - I could talk with people who say they live in Europe, or Asia, or Africa, or wherever...
At that time, for a small window, "We" were one peoples of this world. As the Hacker's Manifesto put it;
"We exist without skin color, without nationality, without religious bias... and you call us criminals."
I await this day to come again. Hopefully the next time, we can meet face to face, and celebrate our differences and come together as one peoples of this world.. But a few of us saw it the first time, for a bit.
