I feel a polarity of people who are deeply controlled by different kinds of fears.
This is what I've noticed as well, particularly in the digital realm.
I resonate with everything you've said here. When people are angry and closed off there's little anyone can do. Life and time is too short for wasted effort. But we can create bridges with those who are open, and perhaps if there are enough then others will be interested in checking them out. Once they've spent a little time with those on the other side who are willing to hear other perspectives, more bridges can be built and so on.
At least, that is my hope. I really don't want to be in a position where I'm forced onto a side. I'm not ready to give up just yet.
Couldn't have said it better!
