When was the first rainbow flag used as a symbol for gay pride?

I say it's time for us heterosexuals to have our own flag, our own month, our own parades and rallies, our own tv networks, etc. I mean fair is fair, all is equal right?

Littlebit, as a heterosexual, I'd say, we've already had all that

Tom, how does it affect you either way? Why should anyone be quiet because they are different from you?
