Not only that, think of it this way. Most of us here right now are pretty chill, we can debate about many topics while remaining calm. However, in big groups there's a bigger risk of douchecanoes, or just very loud people with... Perhaps "wrong" opinions. When one of these people stirs the pot, there might be many, reguarly calm, old subscribers that jump in. In the end, some people being obnoxious end up making other people obnoxious too. Those are my two broken English cents.
