I don't get annoyed when they ship m/m, i just hate it when they get annoying about it. I ship m/m f/f and m/f but yaoi fangirls like to shove it down your throat that only their ship is the proper ship and if you ship anyone else you don't know the fandom. That doesn't even include the fact that they are usually crazy. They blatantly ignore canon and then put anyone who enjoys canon down. And there is the whole "if you don't like this yaoi pairing it's because you are a homophobe" shit. No bitch, i don't like Wincest because they are fucking brothers, not because i'm homophobic.
Basically, ship who you want idgaf, but don't be annoying about it. I hate that.
