Not really history. For much of the 6000 years of recored human history homosexuality was condoned by most culutures, ie greeks, romans, babylonians, persians, egyptians... It was Jews in the ancient world who condemned it (one reason they were hated so much) and then Christians. All we are doing is going back 2000 years when we accept this behavior.
Much (propaganda) has been made of our modern view of the ancients accepting homosexuality. However we ignore the context, the ancients did not believe woman to be the equal of man, women were viewed as being fit for child baring and little more, ergo, women were unworthy of a mans' love. Real love was between equals not the superior man and the inferior woman. But to them love did not equal sex. Sex was for man and woman, love was for man/man. A man could love another man and never have sex with him. At least that is my take on the ancient educated Greek view of the proper role of the sexes.
