The most frequent claim these people would make would be something along the lines of "Shipping a M/F pairing is homophobic because [x] is gay!!". It'd often be phrased in a more general way such as this Tweet or be something more targeted under posts of heterosexual couples.
While this one isn't bad and the artist actually likes/draws a hetero ship, I want to highlight the "CW // #yaeyato" at the top. For those that don't know, CW stands for content warning, and posts with CWs commonly are spaced out with a few periods like the artist had.
The biggest thing, though, was on Archive of Our Own. There was a "war" there where YaeYato shippers would write fanfiction and incorrectly tag/summarize it. It would seem innocent enough by that alone only to be some weird rape fic. This is one thing where you'll have to take my word and this Tumblr screenshot for since I'm sure these were mass reported or something.
It had turned into a thing where it's harder to find the people that will scream about the ship and more people trying to dunk on the haters, but it gets pathetic on the "pro het ship" side, too. Someone made a whole Carrd dedicated to defending it back in March. While the URL (
https://yaeyato.carrd.co/) still works, it seems like someone took it and replaced all the content with "lmao" and nothing else, so it's not worth trying to archive.
