wiki in English on the nun. Doesn’t mention her engagement.
Hmm. My translation has nearly the opposite. After Enkidu dies, Gilgamesh goes into mourning:
Wait … so Gilgamesh was a lesbian?
Gilgamesh sheds his hair in mourning after Enkidu dies, but the text does say a couple of times that Gilgamesh “loved him like a woman.” Maybe that was a figure of speech in ancient Sumerian.
I vote to exclude people from the ancient world. Their categories of sexuality were just not conceived of in the same way - I agree with Halperin.
And I can’t say that I see ‘homosexuality’ in a modern sense in Gilgamesh or even in Homer, really. (Obviously the Athenians thought there was homosexuality in Homer, and there were apparently some interesting arguments about who was the erastes and who the eromenos)
I would really like to twist The Flying Dutchman’s question a little (sorry, Flying Dutchman) and ask who outed themself, or was outed, in at least near-modern-times and got away with it. Career undamaged, reputation intact or enhanced. When did this become possible and who was the first to make the jump?
Homersexuality?
Well, in some interpretations, didn’t Ham make butty with Noah? He was really outed. Like outed to Africa.
From Ham’s wiki page,
You want to make inroads in the heartland, give up those fruity appliances and go with a deep fryer.
Hence the origin of “frottage cheese”, discovered by some uncircumcised Greek lads who were not careful about under-the-hood cleaning. It was later marketed as “cottage cheese” to make it more saleable. 
well, here’s wiki’s cheese. Intersting, I had always thought it refered to rubbing in public, say a crowded elevator or subway
No, no! I need a toaster oven. And I’m a straight chick, yet I did convert one in my youth (I’m just that good). So please put the toaster oven in the mail, I’ve been waiting.
This is an interesting question. It will all balance on just what constitutes “getting away with it”.
In a very narrow sense, Wilde was allowed to “get away with it” upon his release from prison. But few would disagree that contemporary society extracted their pound of flesh from him.
I don’t know enough about Capote’s life to nominate him with complete confidence … but perhaps he’s one to consider?
German sexologist Magnus Hirschfeld (1868-1935), founder of the the Scientific-Humanitarian Committee, the first gay rights organization.
English author Edward Carpenter (1844-1929), who was candid in his autobiography My Days and Dreams (1916).
Was he a homosexual, though?
Yes. And see the caption of the last photo in his Wikipedia article.
Hirschfeld’s predecessor, Karl Heinrich Ulrichs:
Natalie Clifford Barnay (1876-1972), poet, memoirst, and host of one of the great literary salons in Paris:
You converted a straight guy to become gay? (Because that’s what the toaster oven is for). What did you do to him? :dubious:
I would agree with the earlier posters who said that Wilde doesn’t meet the OP’s requirements. He went through two court cases where the very point in issue was his sexuality, and in both he challenged those who were arguing he was gay.
The first was the defamatory libel prosecution he brought against the Marquess of Queensbury, the father of Lord Alfred Douglas. The Marquess had left a card at Wilde’s club, addresed to “Oscar Wilde posing as a somdomite.” (The Marquess’s expensive education evidently hadn’t included spelling lessons.) In that action, Wilde denied under oath that he had had improper relations with Lord Alfred.
After he lost that case, Wilde himself was charged with indecent conduct. He went to trial and denied it, but was convicted. After serving a hard sentence, he left for France and died there, his reputation in tatters. His wife changed the name of their two boys to shelter them from the scandal.
So in summary, Wilde fought two court cases in which he denied his homosexual tendencies; and having been convicted, found his career ruined and his personal life shattered.
That doesn’t sound to me like the OP’s requirements were met.
