It is so horrible, actually, it's why I have the pink triangle as my side avatar - taking that symbol and marking myself with it. I'd rather wear the pink triangle out of pride than out of fear.
Pierre Seel was the last known surviving French gay man who was a victim sent to the Nazi concentration camps, he died not to long ago - November 26, 2005 at the age of 82. He wrote a book about his experience, which was translated into English (here is an excerpt):
"All the inmates were summoned to stand at attention in the camp's assembly ground. The camp commandant and all his troops were there. Into the center of the square we were ordered to form, two SS men dragged a young man. With stupefaction I recognized my beloved, Jo -- he and I hadn't seen each other since a few days before my arrest....The loudspeakers played noisy military music as the SS men stripped him naked, and violently jammed a metal bucket over his head. They unleashed on Jo the camp's ferocious guard-dogs, German Shepherds, who began to rip at his flesh -- first his genitals, and his thighs, and then they devoured Jo before our eyes. His screams of pain were amplified and distorted by the bucket over his head. Frozen in place and trembling, wide-eyed at seeing so much horror, I had tears running down my cheeks. I prayed that he would rapidly lose consciousness...."
The book is called: "I, Pierre Seel, Deported Homosexual: A Memoir of Nazi Terror" (English version). You MIGHT be able to find a copy at Amazon.com (I see one is selling for $99.

If I had the ability, I'd make this required reading for any High School Students studying WWII. (Hell, I'd make it required reading for all of America.) At the very least it should be required reading for all LGBT Youth, it is sad - but I think if we aren't careful we'll lose our history. Unlike Black people we can't really "pass it down" through the generations as we would in a family. Each new generation seems to be oblivious to the last, and end up making similar mistakes as a result.
