My main problem with the genderbends is the fact that when i'm looking up a certian pairing (Yaoi, Yuri, or straight), mainly in fanfiction, i end up finding one that looks good, only to click on it and have it be all "LOLOLOL GENDERBEND.".
If i'm looking up Hungary and Austria, i want some damn Hungary and Austria. Not this bizzarly written yaoi fanfic with Hungary as a guy. Or if i'm looking up Germany in Italy, i don't want to see one or both of them as female, i want to see just normal Germany and Italy.
This is all, of course, in my opinion. I guess it's just the fact that i'm so used to seeing the guys as guys and the girls as girls, it makes it a little weird for me to read it and try to think of them as opposite sex.
Or maybe i'm just PO'd that FF.N doesn't have a yaoi, yuri and straight filter yet. Because that would be awesome.
