Quite bad that it's even needed, actually. XD To those who don't know: I'm bi. And have a girlfriend. Not that it matters, but it'd be useless to make this post without coming out myself. XD I usually don't officially do it, because no-one will go: "Hi, I'm *name* and I'm straight!" So why should people of other sexualities have to? (Worst thing about "coming out"? It never ends.)
Hopefully one day days like this aren't needed anymore, and things like gay pride will be a thing of the past. I still believe that in the future everyone will simply accept it. They did it in ancient times, so I don't see why we can't do it again.
And to anyone (apparently including many of my relatives; lovely to know) who thinks it's a bad thing:
