Why is the game community so lgbt?

Not to sound disrespectful or anything, I just really enjoyed the game and I'm omw to get golden strawberries. I also love to see speedruns and mods/custom maps of the game, but while looking into it I have found myself with a gigantic amount of lgbt content which I don't quite understand its origin. As far as I remember the story is more of an anxiety/depression kind of deal, so I really don't know where it all comes from. Again don't wanna sound disrespectful just geniunly curious
