I know there are a great deal of normal respectful people in tumblr....but "don't group us with this extremely large and overly vocal group that is the dominant force in our group" is like saying "I'm not one if those guys" or "I'm not like other girls" .....if you have to say it, too late, tarred with the same brush.
Edit: to clarify, I'm not attacking tumblrites in general. Just pointing out that the large angry mobs give a bad rep
To be fair, a very large, very vocal part of tumblr thinks the BSN is a raging pile of horsemanure and prefers the small handful of SJWs on their dash over the raging flamewars they believe to happen here.
So tumblr hates the BSN. The BSN hates tumblr. 4CHAN hates everyone. And the Dragon Age subreddit occasionally sends out brave explorers to these other sights it hopes that they'll return unharmed and bearing new information/fanart.
The things that tend to leak out from any of these sights to other parts of the internet will never paint them in the best light. People are always more inclined to notice the drama over the polite, civil interactions that actually make up the majority of posts, because drama is more interesting and eyecatching. Especially when any new drama from these website feeds into their confirmation bias.
