That's like saying pointing out that a man is missing a toe is exaggerating how disfigured he is. Someone claimed he wasn't disfigured, so I pointed out the toe. Ignoring it doesn't make him less disfigured.
No, you pointed at an abnormally hostile minority and, despite all logical process after you said that it was more hostile than normal, concluded that the entire community is hostile based on that sample.
To put that in line with the quoted analogy:
You pointed at a man who's missing a toe and conclude that everyone in his vicinity is likewise disfigured.
Now, I will readily admit that I have not been following the DAI forum sections much (avoiding spoilers prior and right after the game release, then didn't bother to follow it after I quit DAI because I don't like the game at all), so my firsthand experience on how the DAI specific part of community acts right now is something I can't relate to. But I've roaming the boards for a long time (started when the BSN wasn't even a thing back then) and my experience has always been the same, people were helpful, mostly pleasant and passionate. Even during the infamous ME3 ending thing, most people were still helpful, mostly pleasent and the whole thing only became as infamous exactly because so many people were that passionate about it. And yes, a couple nutjobs are always there to blow everything out of proportion and generally being assholes. They were there during ME1, DAO, ME2, DAII, ME3 and undoubtedly now with DAI. The same kind of people are also present at any other existing community where people are passionate enough to care and express their opinions, as extreme they may be sometimes. ANd some of those people can be very, very vocal, but they still won't speak for the majority.
