Responding to the much earlier theme of political activism...well that's a tough one for me. I usually avoid politics because it's...well...unappealing. Seems like if you're looking for the quickest way to get a bunch of adults to act like self-centered, needy, demanding two year olds, just introduce a political topic. This is especially true if you happen upon one of the many topics which inspire, shall we say, more passion than carefully considered thought (and yes, climate change is exactly that for a lot of people.) The point of politics appears to be perpetuating an almost religious sense of self-righteous moral outrage, and I just don't have the patience for it.
Now having said that, I've found some resources for US-based issues (and clearly, politics and geography are linked.) They tend to focus on developing/supporting solutions which are less divisive than proposals which would propel candidates from either party into office--and hence less newsworthy. I'm currently using these resources as a way to keep tabs on what approaches have a chance of surviving a change in administrations. They're also a way for me to choose what to focus on and learn more about. Conversely, I almost automatically filter out proposals from individual candidates as self-serving noise. The big things need to be supported by well over half the country.
Here are some links I've found helpful:
And for data + statistical analysis on an almost haphazard collection of topics...
I hope some of these links are helpful to others who find US politics distasteful. Feel free to share resources from your region or other resources for the US.
