Woah, woah. Hold your horses.
I do understand people having a hard time confessing to someone else being gay or het. What I don't understand is why every story has to pull the same keynotes. It's like the Canon by Pachelbel of yuri. Aren't you even a bit baffled that something supposedly out of the ordinary always develop in the same way? It's like watching the ninth reboot of Spiderman.
Oneshots are that, oneshots. You don't have to wait for months to find out that the story didn't develop an inch or in fact it went back to square one and all this while you fear the author pulling the same old yuri tropes again and again.
This has nothing to do with not understanding the degree of homophobia in Japan or anywhere else. It has to do with the quality of the media being discussed. If you think that yuri should get a free pass whatever the quality just because it is somewhat gay maybe it is you who should check your privilege.
