The Dragon Age Confession mod got a "Die Straight *****" message in her fanmail because she would not post a confession that wished death on straight people. That blog is very LGBT friendly....but then people get mad because she wont post hate confessions on straight people.
I've seen the opposite happen when someone supporting the idea of Cullen's bisexuality ended up with pages of anon hate and angry ad hominem attacks. Some people just get way too aggressive and riled up about things.
My introduction to the Dragon Age series has also been my introduction to the world of fanfiction and headcanon because up till this point I've only had to deal with my own versions of events in my favorite games. The multitude of options we get in this series makes it essential that we, as fans, learn to separate our personal worlds from those of others. It's not possible for any of us to enjoy interpreting events the same way as someone else given all our choices and personal preferences. While some things are presented to us as canon in dialogue, I don't see why anyone else should ever feel the need to attack someone for wanting to envision their own scenarios provided there's nothing to prove otherwise. And even if there is proof, who cares? People should be happy in their own heads.
It doesn't even matter what "side" they are on at this point - everyone just needs to learn to chill and keep a level head, like narcia says. The way some people have dealt with their disagreements is the real problem here. Hopefully this debate will die out in the next few days since Lola's enlightened us all.
