Fullmetal Alchemist AND Fanficrants: Two For One Special!
A whole bunch of this got deleted in the mid-afternoon, so I'm going to work off of what I have at hand.

hawkeye_chuui posts a topic in fanficrants going on and on about how Roy/Riza is the shit because it works, where as Roy/Hughes, Roy/Ed, and Ed/Al doesn't really work at all. The OP makes it clear that she doesn't want wank to set in, but by early afternoon, the wank sets in with a variety of cries from the fandom trying to justify what they ship.

The post is later edited to say that since the commenters didn't play nice and they suck at being mature (though most of the comments were mature in the first place), the comments were disabled, and the post was deleted.

It's over, right? Wrong.

indefatigable42 shows up, guns blazing, and looking for a fight, since the commenters didn't get to defend themselves before the post was deleted. She closes with this final note:

It's a pretty tall order to ask everyone involved to just forget it ever happened, and I'm sorry we didn't get the chance to resolve it like adults. You weren't the only one justly or unjustly accused of anything in there.

Meanwhile, hawkeye_chuui tries to defend herself, which doesn't cause much wank until a Mouse shows up with a link to devils_devotion rallying the minions.

Spread out wank happens in devils_devotion's journal, the highlights being:

x. All the Royai fans SUCK!
x. Rossette's character is ruined for me!!1
x. Remember when this fandom was fun?
x. Hawkeye_Chuui's fanfics are TOO fluffy!

To summarize, since this post turned out longer than I wanted it to be: Saying you don't mean to cause wank over such a wanky subject will not avoid the said wank. It'll happen anyway, especially if the subject fandom is Fullmetal Alchemist and it's OTPs.

(Also, please note that none of my opinions were included in this :P I'm just posting it.)
