What Concerns You Most?, along with some choices of concerns. See FreeThinke's post for the list.
I weighed in under the category of Other.
Here is my biggest concern, applicable not only to politics:
What concerns me most is the ever-increasing inability of adults to consider evidence and draw a logical conclusion based on that evidence. People today are locked inside their ideological boxes and are unable to think outside of those boxes.
Even worse: instead of thinking, people whose cognitive bias is challenged do everything possible to silence the messenger.
Two questions for commenters:
1. If my concern is accurate, what is the remedy? Is there a remedy?
2. Do you have a different greatest concern?
