The mistake you - and way too many other people - are making is in viewing social media as a place to find your "tribe." This has been pointed out as the principle problem in the western world since 2000 or before: social structures are fraying to the detriment of our health (mental and otherwise). Facebook friends aren't friends. But we treat them as if they were. The mistake you're making is assuming that you can have a substantive discussion about the issues with a group that has effectively no ties that binds them to you. Go to a precinct meeting. Have that conversation with a random stranger... in person. It'll go a lot differently. Simply by being in the same room physically you're a lot closer to their "tribe" than anybody you graduated high school with ten years ago.
