Hmm, I hate to say you're imagining things, but I'm not sure I have the same perception you have. I feel like things have been fairly quiet in my corner of hubski. There haven't been any recent reddit refugee crises that I'm aware of.

Edit: I would just add that I have seen some of the more heated discussions you've taken part in recently and I think that's just par for the course; there are certain topics that do engender a more lively debate, and it's often easier to focus on the disagreement and dig the 'ol ideological trenches so-to-speak, but I think as the newer members get to know each other, and the older ones to newer ones, disagreements will tend towards civility. At least, that has been my experience of off and on lurking over the past two years here.
