Evolution of Yaoi

Kaze to Ki no Uta by Keiko Takemiya was published in the 1970's and true to the time ends horribly (in death).

Junjo Romantic by Shungiku Nakamura was written in 2002. (The English versions which came out in 2008-2010 made it to the New York Times Best Seller lists)

Episode 1 you can see some of the criticisms people have against Yaoi.

But now compare that to Yuri on Ice where the same sex love is simply in the background. There's no denial of homosexuality, no abject horror of same sex relationships only a concentration on Yuri succeeding. It's about him accepting who he is and he does this by finding the joy of skating and love.
