...I can't believe you chose Bleach and Harry Potter of all fandoms as your examples of fandoms where "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".

You know, the Bleach where IchiRuki and IchiHime shippers are at war 24/7, and the Harry Potter where the Harry/Hermione fans are by far the loudest and wankiest?
