First, let me set things aright - Sunstone is being facetious, by using sarcasm and irony. Obviously, someone mistook his post as being a condemnation of gay people as being in a serious vein. Apparently, Druidus' comment was a little to vague for some to grasp.
Oscar Wilde, Da Vinci, Alexander the Great... the list of gay people that were creative geniuses is almost endless. It definitely seems that the 10% of the population is extremely well represented in the ranks of creative genius. As for people that are more contemporaneous, I'll throw out the names of Elton John and Michael Stipes as being in this category.
Certainly, the most heroic of famous homosexuals has to be the entire Spartan culture. This is the Greek city-state that produced King Leonidaes, who led the three hundred Spartans to hold the pass at Thermopolae (the Gates of Fire). They stopped the Persian army for almost an entire week, while sacrificing themselves to save Greece. The entire culture of Sparta embraced homosexuality as a normal function of daily life.
